The London, UK-based carrier operates a 30,000km MPLS network across western Europe and into eastern European countries such as Poland and Hungary, the capabilities of which underpin the service it plans to launch next month. Interoute CTO Matthew Finnie said an MPLS VPN can remove all the complexity of the PBX-to-gateway-to-router configuration normally required to integrate legacy circuit-switched connections at the customer premises into an IP network for VoIP services.
He said the idea is, via MPLS VPN technology, to suck all the PBX intelligence into the network, enabling personalized call routing at the subscriber level, resulting in the follow-me service based on the number the individual carries with them. It’ll be like corporate Skype, Finnie said.
The first step towards such an offering was to separate the access or bearer technology from the call, such that using a PBX with a PRI [ISDN] connection to a softswitch shouldn’t mean the loss of voice VPN functions like personalized call routing.
Recognizing that the world of access is still heterogeneous, Interoute converts all the legacy signaling traffic (Q.391, C7, and H.323) at the edge to the Session Initiation Protocol now becoming standard for VoIP. All the intelligence from that point on becomes SIP-based, which in turn makes possible not only the personal call routing service but also, down the road, presence. In the second half of this year we’ll launch presence and the ability to publish to others, said Finnie.
