Unifd Communication:The evolution o dynamic collaboration

ABSTRACT

Unifd Communication rrs to a vry simpl idal, ncapsulatd in th ollowing dfnition:

Intgration o ral-tim communication srvics such as instant mssaging, prsnc,

tlphony (all orms), vido conrncing, call control and spch rcognition with non ral

tim communication srvics such as unifd mssaging, (mail, voicmail, SMS tc).

Unifd Communication is not a nw concpt; it was frst mootd in 996 whn th frst

Intrnt Phons (iphon no lss) and IP-TDM mdia gatways startd to appar.

Th common nablr or all o unifd communications was th dvlopmnt o IP-basd

signalling protocols; initially H.323 and thn standardisation ollowd around SIP

(Sssion Initiation Protocol). Th ky bnft whn using IP ovr TDM is sparation o th

mdia (your voic/vido tc) and th signalling. In simpl trms the way you fndth othr

prsons communication dvic can b sparatd rom how you send th contnt o your

call; this maks th ability or dirnt dvics to talk togthr a managabl problm.

Th sparation o srvic and transport is th undrlying principl o all Nxt Gnration

Tlcoms and th cornr ston o Introuts Unifd ICT stratgy. Unifd Communication

crats a world whr communication dvics o any tchnology can communicat dirctly

with ach othr, thrby uniying your world o communications. Th sparation gos

urthr as it mans that YOU ar th prson bing calld, not th dvic you rnt, this

ctivly ovrturns 00 yars o tradition whr th dvic (and its associatd numbr)

is actually what gts calld, not you th subscribr. You just happn to hav it in your

pockt or on your dsk. With Unifd Communication it is th subscribr (th individual)

who is calld and thir prrrd, dault or only mthod o ral-tim communication gts

th call, much th sam as it is with wbmail. Just as with mail, it is th addrss/numbr

itsl that acilitats th abstraction layr btwn usr and dvic.

Th broad bnfts o Unifd Communication ar obvious complt usr mobility,optimal (low cost, high quality, or indd th rvrs) call routing, rationalisation o

Unifd Communication: The evolution o dynamic collaboration |2




In recent times the spectre o Unied

Communication has been most realised in

the consumer space; this has lead to three

quarters o UK workers wanting to combineemail, voice, video and instant messaging

(according to research company Redshit),

73% said it would make the workplace more

ecient and crucially expand the work

environment, enabling them to work outside

the traditional work place. This is coupled

with a steady increase in the number o

laptops connected to mobile data networks:

rom 26M in 2008 to a orecast 36M in 2009.

The trend and the demand are or more andmore integration, simpliying and uniying

communication.

This whitepaper outlines the challenges,

solutions and most importantly the method

by which an IT manager can get on the

road to the communication nirvana, while

still maintaining service and expanding

the communication capabilities o their

organisation in a risk-ree manner. In doing

so they will cast o the shackles o yearsand years o restrictive practice.

It also introduces Interoute One, which is

Interoutes unied communication platorm.

Interoute One can be thought o as the

largest communication cloud service in

Europe delivering over 7Bn minutes a year or

carriers and enterprises alike. Interoute One

rewrites the rule book when it comes to how

communication services should and can be

thought o by eliminating the technologicaland commercial barriers that separate the

worlds o wholesale and retail voice services

Loty Goals and Modst aimsThe desire to evolve communication in

the work place leads to conficting and

sometimes conusing goals. On one side

users want to be able to communicate reely

without constraint, but the IT manager and

probably the CFO want to be able to use

Unied Communication not only to improve

productivity, but directly and positively to

impact cost.

The simple challenge or most IT directors is

where to start? The problem and challenges

aced by the IT manager is three old:

Lack o standards two very dierent

worlds; the world o PBXs and Computing

Regulation what can you do in each o

your oces, whats possible? whats not?

Concerns over technology: VOIP and its

readiness or corporate communications

Standards

The world o corporate telephony has or

years existing in the twilight world o ITU

standards; with copious vendor extensions

(to add decreasingly valuable eatures),

meaning in practical terms that i you want

to realise any level o sophistication and

inter-working in your corporate telephony:

youd better buy rom the same vendor. This

very simple sales approach or PBX vendors

that has served them well over the years.

However; ew enterprises will nd themselves

in a position with a consistent single vendor

environment: acquisitions, changes inmanagement and varying economic cycles all

serve to complicate the lie o an IT manager,

typically leaving them with a mix o vendors.

This reduces most PBXs to simple Private

Branch Exchanges (PBX) distributing DDIs

among a series o extensions.

3/22





The lack o network and the cost and

complexity o building a dedicated voice VPN

means most never even realise the ability to

have ree on-net calling amongst oces.

SIP is the IETF standard that underlines

Unied Communication and creates a world

where the call control resides centrally.

It eectively has evolved to translate

traditional TDM protocols, allowing or the

mixing o traditional TDM technologies and

pure SIP-based communication. It allows or

the creation o communication platorms

that are agnostic to the technology o the

communication device, allowing traditionalblack phones to talk to PCs and vice-versa.

Unlike previous standards; SIP is resolutely

open in the grand tradition o TCP/IP, MPLS

and Ethernet. For Unied Communication to

ever work this was, and still is, a prerequisite.

Rgulation

Unied communication is the confuence o

two disparate worlds: the unregulated world

o applications and the Internet, and the

tightly controlled and until recently state

owned world o telephony or PSTN (Public

Switched Telephone Network), or in the

simplest term, phone numbers. For years

this has lead to conusion over when a VoIP

application should be regulated and when

it shouldnt. Unortunately there is no silver

bullet that addresses the issue. Whilst you

can browse the Internet pretty much

anywhere in world (with varying degrees o

constraint), the same theory does not applyto Unied Communication. Email addresses

are the domain o the enterprise but the

phone numbers are owned and regulated by

the local incumbent or second operator. You

can make a VoIP to VoIP call anywhere in the

world (unless they block UDP the requisite

protocol) but can you break out to the PSTN?

Sometimes yes, sometimes no.

The challenge or the IT manager is: how

do I eliminate the geographic constraints

on my organisation and normalise the

communication environment? There are overa billion xed phones and a billion mobile

phones in the world [The Yankee group]

so communication between all orms o

technology is essential i the move to unied

communication is to be eective.

Concrns ovr tchnology VOIP: its

radinss or corporat communications

Since 1994, when the rst Internet phones

emerged, there have been concerns and

comments concerning the quality o VoIP-based communication versus the traditional

Plain Old Telephone System (POTS). The

concern is reerenced in the world o the

Internet and is related to the variability o

quality in the call and the ability to maintain

consistent call quality. 16 years on, and

the world is considerably dierent. Billions

and billions o everyday calls are transiting

IP networks, which are mostly privately

controlled and managed using MPLS. The

largest mobile network in the USA is SIP

based [AT&T] and all the growth in minutes

is on SIP based inrastructure [Interoute].

Uncharacteristically it has been consumers

that have led this development and it is now

time or Corporates to catch up.

The issues with extending this into the

enterprise are oten bound up with the way

in which many o the equipment and service

vendors orientate their solutions. Many

solutions sold to enterprises continue to place

the intelligence outside o the network, i.e.

create more sophisticated PBX inrastructures

at the edge o the network. This approach is

outdated and harks back to the days o closed

networks, where you had little choice but to

place intelligence on the edge o a network.


4/22





The rise in scalable and intelligent

MPLS-based cores, most notably recently

with Interoutes development o Unied

Connectivity, create a service environmentwhere enterprises can leverage carrier-grade

networks and sophistication, directly creating

a controlled, intelligent and access-agnostic

platorm or the development o services. Ater

that the only challenge or maintaining quality

or VoIP is exactly the same as or TDM: you

need to have adequate network available to

ensure call quality. The added advantage o

the SIP approach is that i you have existing

TDM services they can be controlled through

your SIP-based inrastructure so preserving

your investment.

How to startThe simple and immediate challenge or

most IT managers is their communications

environment is complex and consists o

isolated pools o vendors and technologies.

The ollowing scenario is typical o most IT

managers challenges. The extent to which

you adopt the solution to its ullest extentis largely a question o taste. Either way

we believe the common actors and the

base solution serve to set all enterprises

up such that they take control o their own

communication strategy and can leverage

innovations as they come along without

major investment. The assumption in this

approach is that the IT manager wants to

minimise the impact to their business,

whilst moving orward he aims to preserve

and utilise existing investments to the ullest

extent. O course i the asset maintenance

is too costly (or example the support costs

on most PBXs e.g. adds, moves and changes

can be hugely expensive) when compared

to the equivalent operation in an Active

Directory, we would always advise

eliminating unnecessary overhead.

Th Goal

Firstly, what ar th goals that typically

motivat an IT managr to considr

Unifd Communication?

Preserve existing PBX investment, but

connect them all together to save money

on inter-oce calls - this could also be

preserved or as long as needed or until

people are comortable with the new

method(s) being introduced

Preserve the companys existing number

range, but allow those numbers to be

directed to other devices

Introduce Unied Communication in the

orm o a product like Microsot Oce

Communicator, add connectivity to the

PSTN, and include video conerencing

Introduce on-demand audio conerencing

reducing the cost o monthly outsourced

bridge services

Be xed mobile convergence (FMC) ready

when the handsets and the technology

mature to ully integrate the mobile and

xed experiences

Be master o my own destiny control

the pace o change and not end up down

any vendor specic technology cul-de-sac

with hety maintenance contracts

Moving way rom the paralysis o: My PBX

estate is mixed vendor. I cannot combine

them, I have no economies in support,

uniying vendors will cost substantial

money and wont radically change the

experience or cost base or my users


5/22





Cost and Productivity

The twin and sometimes contradictory goals

o reduced cost and improved productivity are

the main drivers behind the shit. Normally

the approach would be ocus on one to

sacrice in avour o the other. However; the

situation with Unied Communication has

now matured to a point where the approach

outlined intrinsically reduces cost and creates

an environment or capability expansion and

productivity improvements.

Cost:

Cost o calls - all oce-to-oce calls

are zero-rated regardless o geography

Flexibility in how you route calls and

re-route calls; or example route all calls

to a central call centre whilst providing

local numbers in country

Reduced maintenance costs: the

administration overhead on your Active

Directory when you add communications

to it is marginal and in most cases zero.

So those costly add, moves and changes

or a PBX are completely eliminated. An ITmanager with a PBX could spend 150k

per year on a PBX with 900 extensions

mainly in adds, moves and changes. The

equivalent unied communication number

would be a raction, probably less than

10% [without a reerence this is hearsay].

Productivity:

Common communication in any location

on any device. Your workers armed with

a laptop and mobile phone can take theiroce with them and maintain a consistent

set o communication capabilities. You can

adapt the communication set to meet with

the needs o individuals. This also means

you can oer wider choice o device as the

underlying method becomes the same.

Lower TCO through common

administration o all communication

services. The unication o communication

greatly reduces the administration o yourcommunication capability. Key in this is

the use o enterprise directory services

e.g. Microsot Exchange

Desktop and phone integration converge

directory services between the phones

(mobile and xed) and the desktop

The method by which you developed

your unied communications platorm

allows you to test the environment

with your users without a big IT bang.This means that your requirements

gathering or rolling out new services are

based on experience, not on prediction

or wishing sessions. You can respond to

specic well-articulated requirements.

This is oten reerred to an agile

approach or iterative waterall, either

way it means you track the users with

many subtle innovations.

Migration MthodThere are many suggested approaches to

achieving the goal o unied communications;

ironically most o them are less about

uniying communications than they are

ocused on replacing one method with

another, which is invariably as equally closed

as their present methods.

You will hear rip and replace the PBX, to all

new IP PBX or Skype only; these phrases

generally advocate major upheaval in theenterprise. This is largely because they are more

about preserving the business model o the

advocate than really addressing the problem.

Even the so-called independent consultants

tend to make much o the analysis o needs

when or most the problems are staring them in

the ace. But USE CASE analysis is a nice little

earner even i all you want is cheap phone calls.


6/22





Unortunately or most IT managers, the 24

hour switch is one most loathed as either side

o the event is months o user adoption training

and heartache as careully laid plans are trippedup by the infexibility o traditional telephone

service, incompatibility o vendors etc.

Below is an outline with a ar less dramatic

approach (not as news worthy either) to

moving your communication orward; one

thatcreates an environment where adoption

and choice is manageable and controlled

by the IT manager. The Interoute approach

is about creating the right environment

or migration. It then lays out how to builda common environment that can then be

adapted at will. Crucially in this approach

it leaves open the question o how much

control you want to manage yoursel and

how much you would want to give to a third

party. Interoute has made much o its success

out o adopting adapted outsourcing models,

allowing or change as businesses trust us

more, and decide specic inrastructure is

more or less important to them. This model

is based on the Interoute product Interoute

One which is an access agnostic enterprise

communication services platorm.

(See the appendices)

Th Migration Modl has our stps

to achiving this

Integrate connect your legacy and

new communication devices together

Separate the signalling and the media

Combine the users identities URI

and PSTN/Mobile

Migrate migrate based on user adoption,

avoiding a technology big bang

Intgrat Communication Dvics

The rst step in getting toward a ully unied

communication environment is to connect

all the devices together. The immediateadvantage o this is that PBX-to-PBX calls

are subsequently zero-rated delivering

immediate measurable savings. Practically;

Interoute will on a PBX-by-PBX and trunk-

by-trunk basis, test interoperability, ensuring

consistent signalling and call quality.

Interoute One is an access agnostic platorm

that caters or up to 8 dierent access

scenarios rom traditional E1 (PRI) to or

Microsot Oce Communicator certied SIP

trunks, as illustrated below. The immediate

benet o this is that call routing can be

optimised rom a cost and quality perspective.


7/22





Intgrat Inbound Numbrs

The thorniest issue with Unied

Communications is numbers; meaning

inbound geographic numbers. As mentioned

beore there is no silver bullet or this.

No-one oers a simple global solution so

each case tends to require a series o

approaches not just one. For example in some

countries it is not legal to port an inboundnumber, so the operator has to get a new

number, or the incumbent regulator does

not numbers to be owned by anyone other

than the actual customer (rather than a

service provider). Interoute currently oers

inbound numbers in 47 countries and has

porting agreements in many. Our approach

is to take the problem o the IT manager and

solve it in a variety o ways including:

Take over the existing contract and

number range rom the incumbent

supplier initially this may require a CPE

gateway on site to redirect the numbers

to Interoute, with a uture migration on

the network side between Interoute and

the other carrier. Either way the problem

is out o the IT managers hands

Port the numbers Interoute simplyports on the network side. In essence

this means that all calls destined or the

customer are routed through Interoute

as the carrier holding the numbers on

behal o the customer

New numbers i there are new devices

being deployed then Interoute can provide

a new set o inbound numbers

Sparat

The next two steps may seem illogical coming

so soon ater integration but they are crucial

in creating an environment where the IT

manager has control. When we say separate

we mean specically the separation o the

signalling and media. This will typically mean

(within the context o the PBX) removing any

routing intelligence rom the PBX. This does

not mean that the expensive Auto Attendant

you just trained your receptionists on is

redundant, rather it reers to the removal o

the directory control in the PBX so that you

only have one control point or services, notmany. The PBXs are now render relatively

dumb and will simply route calls. In many

cases i there is a mixed vendor PBX estate

its probably all that can be done.

Combin

Having rendered the PBXs dumb you now

need to centralise the intelligence. This is

achieved through your directory services

environment e.g. Active Directory. The

simple goal is one directory service or yourenterprise environment. Given the Active

Directory or your mail and messaging will

be more sophisticated and control proling

etc, it makes most sense to consolidate here

and not preserve two separate services which

makes policy maintenance problematic. In

many cases the Active Directory environment

or most enterprises is already populated with

the various mobile, desk and other phone

numbers. Also, when considering the typical

maintenance cost o an outsourced PBX,it reduces costs considerably to uniy your

subscriber management in this way.

Migrat introducing nw tchnologis

Lets just review what has been created

Common communication network or

all connected enterprise assets, typically

the PBXs. You have connected your

PBXs to a communication network so

the intelligence is now in the network,

meaning local breakout on PBXs is

an unnecessary approach when a simple

sot routing change can achieve the

same optimisation o routing.

Benets:

Free on-net calls

Simplied supply chain management

Reduced maintenance costs instead o

maintaining two directory services and

two sets o technologies you now have

absorbed the maintenance o subscribers

into one directory service

Ability to pick and choose how you add

new technologies and services. The ability

to retire or preserve at will - PBX assets,

or replace with a whole new SIP trunk

inrastructure. The users can be given

everything or selectively one method at a

time etc. Control o this is sot and can be

moved, added and changed at will as part

o normal IT processes.

Migration and introduction o new services

now becomes a series o small incremental

projects. The key aspect o this approach is

that you can go as ast or as slow as you like

you have control. You are not beholden to

an operator to port numbers, or supplier toinstall network etc.

Cas Study IntrnationalUnion or th Consrvationo Natur (IUCN)This case study details a recent customer

o Interoute, who approached us with a

challenge: Unied communications or

its entire sta.

What is IUCN?

IUCN, the International Union or

Conservation o Nature, helps the world nd

pragmatic solutions to our most pressing

environment and development challenges.

It supports scientic research, manages

eld projects all over the world and brings

governments, non-government organizations,

United Nations agencies, companies and

local communities together to develop and

implement policy, laws and best practice.

IUCN is the worlds oldest and largest global

environmental network - a democratic

membership union with more than 1,000

government and NGO member organizations,

and almost 11,000 volunteer scientists in

more than 160 countries.

IUCNs work is supported by more than 1,000

proessional sta in 60 oces and hundreds

o partners in public, NGO and private sectors

around the world. The Unions headquarters

are located in Gland, near Geneva, Switzerland.Th challng

IUCN, by the very nature o their endeavours,

are widely distributed globally, and mobile

in terms o their workorce. I they were

to introduce improvements to their

communication capability, they wanted it

to meet the demands o their mobile and

distributed organisation and not constrain

capability through the technology. The sheer

level o distribution means that economicallyPBXs are increasingly expensive simply

to distribute calls, and also tie the IUCN

employee to the desk. The introduction o

Microsot Oce Communicator means that

wherever the user is connected is where the

oce is then. This fexibility and complete

shit in paradigm would achieve a reduction

in cost, and productivity gain.


10/22





Th IUCN Unifd Communications

Challng

The gain is compelling but OCS is new and

or many, a complete departure in the steady

and staid world o oce communications.

So rather than embark on a brave and radical

overhaul o their communication environment

which would have a real eect on all their

users, they wisely laid down a simple yet

seemingly illusive requirement - IUCN wanted

to control the roll out: at their own speed.

They did not want to rip and replace the PBX

in one go (no matter how cathartic it would

be or the IT manager to skip it) they wantedto migrate users gently over to the new world,

with the option to swing them back i it all

started to go wrong.

At this point we have to recognise that

changing user behaviour and their preerences

are not always bound up in the pragmatism

o making technology choices. We have seen

users reject sot phones simply because they

dont like headsets welcome to the world

o the end user. The point is you can never

be sure that users will adopt as you predict,

thereore retaining the option to simply roll

back is always very useul. The simple rule o

thumb with most communication technology

adoption is that users are drawn toward speed

and convenience, ewer clicks, less movement

etc and they will adopt in time. In the case o

communication, the critical user eature is the

integration o the directory into the device.

The success o products like Microsot Oce

Communicator is 90% convenience. You see acontact either in a document, email, or contacts

directory and you can call them on any device

as a result o the tight directory integration.

Mthod

Interoutes rst step in creating the

environment to allow or a user lead migration

was to integrate the IUCN PBX inrastructure

into the Interoute platorm. In the case o

their head oce in Geneva this required

Interoute to take over the existing local PRI

interconnect with their previous operator.

To avoid delays normally incurred when two

operators migrate assets between them (you

can imagine its never a high priority or the

carrier losing the business to speed up things

or the new entrant), Interoute placed a CPE

on site to redirect the pre-existing numberrange so that Interoute eectively became

the carrier. Interoute then post-connection

manages the ultimate migration rom the

previous carrier to Interoute. But critically

IUCN are insulated rom this.

IUCN then connected their Microsot

OCS Mediation Server via a Microsot

Certied SIP trunk rom Interoute. This

element o the migration really illustrates

the shit in capability rom the old world

o xed PRIs to the capability available

through SIP trunks. Anyone with access

to the Internet can connect by going to

http://www.interouteone.com/.

IUCN now had the ability to give all their

users both PBX and Microsot OCS capability.

To eect a user-riendly migration, they

redirected the existing inbound PBX number

to the users OCS accounts. This meant they

could swing over each user department-by-

department, sae in the knowledge that any

issues could be managed and users can be

rolled back.


11/22





Th Outcom Th Futur

Thankully the outcome has been everything

the IUCN team hoped it would be. They are

progressively migrating their users over to the

new world o Microsot OCS and so ar they

have no one yearn or their black phone to

replace the mobility and intuitive nature o

OCS. One o the key opportunities once this

initial migration is complete is the opportunity

to expand beyond the initial 1000 employees

and seek out ederation with other members

o the IUCN expanded community.

The idea o ederation is a secure exchange o

directory inormation so that you can extend

the same benets that you have with your

own community to your associated partners.

Taking this to its logical conclusion, your

on-net community thereore will expand

progressively. Imagine i all the organisations

globally who use Exchange, integrated

OCS and repeated the IUCN experience.You then create a secure and controlled global

community o users who can collaborate

reely without watching the clock (minutes

means money).

ConclusionUnied Communications should not be

thought o as a product or a single program,

but a way o thinking about communication.

It assumes that: there will be no boundaries to

what and where you can communicate, users

will customise their user experience around

their preerences, i I have invested once in

managing my subscribers I can reuse that

investment, and that I can get as sophisticated

or simple as I preer and change my mind in

the process.

The change in the past 15 years means that

the traditional ways o thinking about how

to implement communications are limited

not by the imagination o the IT manager,

but mainly by the business models o the

traditional suppliers who have been

reluctant to change given that intuitively

uniying your communications immediately

rationalises your cost base.

Interoute has developed its platorm over that

last 7 years and now manages 7Bn minutes

a year o other peoples trac and realises

that there are no greenelds and perectstorms into which we are slot our capability.

Corporate communications is like a short

history o technology evolution, so you have

to be able to move rom disparate closed

worlds to one simple and easy-to-manage

unied one. This approach we believe can

achieve this. It is only the starting point,

so doesnt address the breadth and depth

o the opportunity once you have unied

communications, but like all good

destinations getting there is hal the un.

Appndix On Introut OnInteroutes Interoute One product is an access

agnostic (any orm o access or device) SIP

based communication platorm. It leverages

Interoutes Virtual Voice Network platorm

that supports over 250 global carriers

worldwide and manages over 7Bn minutes

per annum. Interoute One unlike most other

oerings is best thought o as an intelligent

real-time communications network. In

simple terms you can plug old and new

communication technology PBXs (any vendor),

IP PBXs or Microsot Oce Communicator

into it and they will communicate betweendevices in the oce, at a home or anywhere.

You can take as much or as little control o

the routing as you require, you can become

a carrier or simply buy a SIP trunk where you

give Interoute the job o routing the call.

The diagram below illustrates the relationship

between Interoute One, Interoutes VirtualVoice Network and the customer environment.

Product Summary

Interoute One covers a range o

capability designed to serve the corporate

communications market, providing A-Z

their own partition and building a dial plan

and bespoke routing.
