Because he wants calls out over his DSL line to chew as little bandwidth as possible. The only way we can do it today is to configure the phones to use only G.729. But then local calls wouldn't be using the much higher bandwidth available on the LAN. It would be nice to be able to configure, for each SIP Trunk, the list of codecs may be used. i.e. All SDP offers that pass through sipXbridge would have disallowed codecs removed. -Paul [email protected] _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
