Telcordia VoIP Routing Registry Sends IP in the Right Direction

Service providers can save valuable resources on their networks with the new Telcordia VoIP Routing Registry, which helps define calls that will terminate on IP networks so those communications can stay on less-expensive, packet-based networks, says Gary Richenaker, senior director of numbering and addressing initiatives at Telcordia.

All calls today on most telco networks are dumped onto the PSTN because networks can’t tell it their terminating on the PSTN or on IP networks, he says. But the Telcorida registry can see it call has a URI (uniform resource identifier), which indicates it’s a VoIP communication, he says.

Telcordia owns and operates the database, and can host the registry, or the telco customer can host it.

Richenaker says the VoIP Routing Registry is an extension of Telcordia’s LERG, which is a database of PSTN numbers. This new registry actually contains both IP and PSTN numbers, so it can appropriately route PSTN-to-PSTN calls, PSTN-to-IP calls, IP-to-IP calls and IP-to-PSTN calls, he says.
