Agenda
• VoIP Peering in a challenging Economy
• Best practices for NGN interconnects:
bilateral, multilateral and federated
• Registry vs. Signaling approaches to peering
• Number portability and ENUM
• Regional and Global Peering trends
• How peering enables new high margin
services: video, high quality audio
• Commercial benefits and case studies

Today’s Telephony Challenge
How to get all the disparate pieces of the global
network puzzle working together?
Peering brings all the parts together
Enable groups of service providers to multi-laterally
exchange calls with each other via IP, based on a set of
administrative terms for settlement, policy and
interconnection
Best Practices for NGN
Interconnects
• Bilateral
– Resource intensive
– Not scalable
• Multilateral
– One interconnect
– Possibility of one commercial contract
– Minimal use of internal resources
• Network upgrades
• Federated
– Members control policy
• Trust
• Commercials
Registry vs. Signaling Functions
Registry
•
•
identifies service provider or
•
entity
– identify actual egress point
•
– Optimize routing
Enables most efficient routing
mechanism
– voice
– video
– push-to-talk
– SMS
– new IP features
Signaling
Enables scalable
interconnection
Signaling Hub
– Enables signaling
management
– multi-protocol,
Challenges
Physical
Transport
Standard IP Peering /
Connectivity
- Public, Private,
Ethernet
Policy, Trust &
Security
Who should calls be
received from & on
what basis? How to
protect subscribers
from abuse (SPIT,
vishing)?
Discovery /
Location
(ENUM Registry)
Which calls terminate
to another VSP, and
where should they be
routed?
Media Handling
NAT traversal and
codec incompatibility
Signalling
Interoperability
How can signalling
interoperability be
ensured with different
protocols, variants &
implementations?
Commercial
Based on policy and
traffic profiles, should
calls be settlementbased or settlementfree (Bill & Keep)?
LNP and ENUM
• Number portability (local, mobile or full) is now
available in US, Canada, Mexico and Brazil
–
–
–
–
All Call Query (ACQ)
Central Registry Approach
Call Forwarding Approach
Typically delivered via SS7/ C7
• ENUM Registries
– Private routing, public registry, carrier ENUM via ACQ
– Can be LNP corrected
– Enables expansion of ACQ to other Registry
information beyond NP
• Features supported (video, wideband codecs, Presence)
• Call forwarding, call forking, non-traditional number
plans
Regional and Global
Peering trends
Regional
•Netherlands - JCC
MSO peering
Global
•GSMA
•i3 Forum
•Brazil - VoIP peering
federation
•UK - BT IP Exchange
•USA - Cablelabs
•Peering Service Providers
New High Margin Services
High fidelity
audio
Video telephony
IM integration
Vanity Numbers/
DIDs
Not just low
cost voice
Peering to IM Service Providers
• Differentiate service from PSTN
• Peer VoIP Networks with voice-enabled IM
communities.
• Call IM communities – by dialing a numeric
phone
– IM user can call back whenever they want.
– Discover/Provision IM buddy numbers
• using a web page.
• Number assigned to the IM client can be:
– private number
– conventional e.164 number
