I mean B) case :) Let me explain an example: - Two users with STUN or public IP so no media-proxy is required in order to get audio properly. - But me (the provider) want to account a call between them (perhaps not for billing, but for any other reason). Solutions for *secure* accounting: a) Use of a media-proxy (but this requires a media-proxy... and I don't want it since it's not needed for getting audio). b) One of both phones use SessionTimer (this depends on the clients, obviously not a "secure" solution for me). c) Me (the provider) use a transparent B2BUA in the middle of the call so the B2BUA forces SessionTimers for leg_A (phone 1) and leg_B (phone 2). Option c) ensures, just with SIP signalling, that the accounting is accurate without the need of a media-proxy (which could add delay and consumes *my* network resources). -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
