VoIP Peering as an Alternative to the PSTN
VoIP Peering – the interconnection between two service providers for the completion of a seamless session between subscribers on their networks
Enabling Solutions Providers may provide transmission, switching, database, settlement, or other services to facilitate the session
The benefits are:
Improved call qualityLower costsNew services
7
Why is so little VoIP Peering taking place?
Few calls will route between VoIP partners
For example, if 5% of US customers are VoIP end users
% of US traffic that is VoIP to VoIP: 5% of 5% = 0.25%
It’s hard work
Identify all peering partners
Agree upon a commercial relationship
Agree upon IP addresses to interconnect
Agree upon private or public Internet transport
Exchange and update numbers with all your partners
Query all outgoing calls against an ENUM-like server
Bill and settle for termination, when required
8
How Does Peering Work in General Terms?
Company B shares telephone numbers and routing information Company A loads information into an ENUM transaction server Company A outgoing calls are queried for matches to Company B numbers Successful matches provide the routing information Calls are routed for termination An enabling solution provider may be required to facilitate the session

Create Accounts
Private Peering Accounts – used for internal network routing
Only visible to the company that created them
Public Peering Accounts – shared with other service providers
Account presence is public – not the information
Receiving Account – Store numbers from partner relationships
Downloads to a TITAN addressing server
12
Manage Numbers
> Numbers can be entered in several ways:> Direct input of numbers via the user interface
> Individual numbers> NPA-NXX
> Input via a text file from the host computer> Under Development:
> SOAP/XML interface
13
Manage Partners
The name and contact details of all Public Accounts in SPIDER are displayed University Numbers are NOT shared or visible to anyone
Requires explicit permission from the number owner For the Pilot:
Core TITAN Operator requests an interconnect to a UniversityThe system manages the progress of the interconnect requestPartner’s numbers and the addressing information are downloaded
Any subsequent changes of numbers are synchronized as they occur
14
Publish Numbers
Publish Numbers has two primary uses:
Combine Private accounts used for internal routing into one Public account
Allow an intermediary (e.g., Arbinet) to ‘publish’ numbers and entry points
Connect to a broader range of partners via Arbinet resources
All changes to numbers are synchronized to the ‘publishing’ accounts
Service Providers can request ‘peering’ with a publishing account

Current Pilot Status and Next Steps
Successfully created a “receiving” account for the central Internet2 TITAN server
Successfully created a peering account for Texas A&M
Entered test numbers via Arbinet’s PeeringSolutions Registrar
Successfully peered the two accounts within the Registrar
Result: Texas A&M numbers and routing address are in the TITAN
Initiate SIP-R or ENUM queries and confirm correct response
Route test calls within Texas A&M locations
Add a second university peering account
Peer, query and route via Internet2 backbone
Add a few more universities to the pilot program
If pilot is successful, extend peering service to the Internet2 community
