What you're describing is conceptually feasible. The AS would be a B2BUA that terminates one leg of the call and originates the second leg. If the AS hosts the RTP proxy, it would insert its address into the SDP. Or the RTP proxy could be off-board.
You mention Lawful Intercept. Are you in fact trying to implement LI, or just do something similar? The reason I ask is that I've always been under the impression that one of the requirements for lawful intercept is that the feature should be "invisible" to the client, otherwise you potentially tip off the bad guys to the fact that they're being monitored. Not sure where I picked that up, so it could be right or wrong. Anyway, the scheme you're describing might not meet that requirement, as the signaling and media paths would be different for a monitored call vs. a non-monitored call. -- Gary Cote www.awardsolutions.com _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
