Official answer from Bandtel "we do not support reinvite without an SDP, this is a grey area in the RFC it is not a rule that is a MUST. on transfer or on hold the proper format is and RTP destination of 0.0.0.0 and the sendonly attribute. The call is dieing because verizon and other DID carriers do not support that either so it is one of those things that SipX/Nortel decided they wanted to do because it says they may do it." So it looks like Bandtel will plain not work with SipXbridge...we should probably update the wiki to remove them or make note that they do not work. -M _______________________________________________ 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/
