Successful Tests Conducted on Dutch SIP Exchange Project

By TMC European Editor

The Dutch Cable SIP Exchange project (SIPX), an initiative of the Dutch cable industry, has successfully tested interoperability between its peering system, provided by XConnect Global Networks, and the Nokia Siemens Networks hiQ VoIP platform.

SIPX is the world’s first cable telephony peering federation project. It will provide its members with an all-IP interconnect so that calls from one network to another by-pass the PSTN and associated toll charges.

An additional benefit to maintaining an uninterrupted IP path is the ability for the participating cable telephony providers to offer hi-fidelity codecs and video telephony on a cross-network basis. 

These interoperability tests have shown that hybrid implementations of ENUM and IN interconnection can work together within a peering federation and this will have a positive impact on the VoIP peering industry.
