Operation of TRIP
A TRIP Speaker(LS) establishes intra-domain and inter-domain “peering sessions” with
other TRIP Speakers to exchange routing information. The peering sessions are established
to exchange routes to telephony destinations. The peers update each other of new
routes learned by them. Each peer may in-turn learn about new routes from other peers
or through gateways registering telephony prefixes to them or through a static configuration
on the Location Servers. The peers also “withdraw” the routes they advertised to
the other peer on learning about the unavailability of the routes.TRIP peering sessions
use TCP for transport
