The iptel group has already defined a protocol, Telephony Routing over IP (TRIP), which solves one aspect of this problem. Specifically, it handles the case where calls need to be routed between domains. It allows for the exchange of routing information between these providers, so that policies can be applied to the resulting data to create a forwarding information base.
However, this protocol does not address all the scenarios of route information exchange between servers. One important scenario is the propagation of routing information between gateways and the signaling servers in front of them. This is also known as "gateway registration". It allows the signaling server to make a routing decision about which gateway to use based on dynamic information about the gateway resources. Vendors have deployed proprietary solutions for this communications interface. A standard is needed. The group will generate a standards track document that defines a protocol (possibly based on TRIP) for this interface.
The group will also generate a MIB document for TRIP.
Note that the group is not working on elevating TRIP to Draft Standard at this time.
1. A proposed standard RFC for gateway to server route exchange.
2. A proposed standard TRIP MIB specification, based heavily on the existing BGP-4 MIB documents.
