A network of depth and breadth
• High capacity long distance network - 43,000km
• Connecting 22 countries, 39 metro networks and >150 cities
• 20 data centres and 19,000 connected buildings
• B2B only – no MNO

SIP Trunks (Enterprise and Carrier)
Functionality
Complexity
37 voice switches
1 softswitch
80% of voice volume (April ’13)
20% (growing) VOIP

• Colt is a member of the ETSI ISG NfV
• NFV is an element of Colt’s SDN vision
NFV is an important step to optimise and
integrate communication services

Software Defined Networking
Colt’s SDN vision is internally defined as “Network Programmability” and has two main components:
1) Bring computing paradigm to networking: make the network elastic,
scalable, on-demand and virtualised
2) Allow Application layer to communicate, through standard APIs, with
the network
The target is to integrate in the long term IMS functions,
UC and other applications within the SDN architecture
• Fully virtualised deployments on our standard compute platforms
• APIs for QoS, CAC, DPI, provisioning, billing etc. to allow
applications and network to talk

Future Voice Propositions
The OTT Question:
B2B ≠ B2C
• Regulatory (emergency calls, LI)
• Functionality (dialplans, CLI, IN, etc.)
• Resiliency (enhanced routing, disaster recovery)
• End-to-end QoS
… but for how long ?
… what about UC ?
… what about WebRTC ?
9
A new Aspect of OTT
WebRTC brings a new aspect into the OTT discussion:
Will WebRTC change the OTT landscape?
Is WebRTC a threat or an opportunity for Colt?
10
What does WebRTC mean for Colt?
• ‘real’ click-to-call
• Extending PBX DDI numbers to the web
• Integration with audio conferencing / WebEx
• Integration with UC and video conferencing
• Contact center solution enhancements
Extend existing products to native web-browsers
without plugins

Phase 1: Service Enrichment
Being prototyped
in Colt !
11
What does WebRTC mean to Colt?
• Virtual PBX
• Next-gen UC
• Next-gen video conferencing
Web-based realtime communication
(… w/o the need for a E164 number)
2/3
Phase 2: Possible future Solutions
How will this impact the architecture
and functionality of the future
communications core platforms?
12
What does WebRTC mean to Colt? 3/3
Phase 3: Future Core Infrastructure
How does the future Voice/VoIP environment look like?
• Large web-servers instead of an IMS core?
• How will WebRTC be integrated in IMS?
What about current developments?
• Do we need nat’l VoIP I/Cs with PTTs or will it be Internet? (*)
• Should we further (heavily!) invest in Number Portability?
• Etc…
(*) we have been asked this question by a PTT!

Summary
• Functionality of SIP trunks is there, next step is to reduce complexity
• IMS and UC platforms covered in the long-term by Colt’s vision of
Network Programmability (SDN)
• B2B SIP trunking less impacted by OTT so far due to more stringent
requirements, but this may change over time
• WebRTC has the potential to impact our future service offering and
infrastructure architecture
• The next 2-3 years will show if WebRTC becomes a game changer
or if it was a simple distraction
