Sprint SIP exchange service launched

Sprint announced its Partner Interexchange Network (PIN – har har) today to provide “business-to-business” wholesale exchange of voice traffic. Sprint’s PIN service allows users who can directly exchange VoIP service between themselves while on Sprint’s IP network.   Since everyone is on IP, they can either lower or eliminate access termination fees and LEC tandem fees.  But will the SIP routing framework support higher-level functionality, such as HD voice or video calling?

Minutes that go through PIN are charged at a lower rate than traditional PSTN networks and PIN is being touted as delivering high-quality, low-cost VoIP exchange to multiple on-net partner destinations and terminations to the PSTN; no fuss or muss with multi-peering arrangements with multiple partners. PIN is also being touted as having the “infinite ability to scale” with support for multiple verticals ranging from wireline and wireless providers to *dingdingding* cable companies.

PIN has immediate appeal to two groups.  Cable companies have been talking about peering between themselves for VoIP calls for a while and since Sprint is cable’s best when it comes to IP this is a natural fit. In addition, PIN provides another alternative for the business hosted VoIP providers to exchange traffic outside of the PSTN.

Since PIN’s infrastructure is based around SIP, the architecture should, in theory, be able to support media types above and beyond a vanilla VoIP call; such support should already be necessary for moving around MMS and other multimedia types in the wireless world.

Inquiries have been made to Sprint for more information as to what it might support on PIN.
