CableLabs (www.cablelabs.com), the technology standards group for the cable industry, has published the PacketCable IP Interconnect specifications. The specifications open up the ability for cable companies to interconnect directly.
Specifically, the two published specs define ENUM server provisioning and how the ENUM server resolves an IP address and CableLabs describes the IP Internet package as enabling “cable operators to consolidate session establishment data used by PacketCable™ network elements to route SIP sessions to the target destinations which may be served by the cable operator’s own internal network or by a session peering partner.”
Session peering partner should translate to “When cable companies peer directly and stop touching the PSTN.”
