Hello, I am testing sending of FAX via sipxbridge. I find that the Audiocodes INVITEs using G711 offer and then Re-INVITEs using a t38 offer but now with a different receive port. However, the session ID for the SDP is the same. Does this mean there are actually separate receive ports associated with the same session?
Attached is the merged.xml which would clarify the situation. Note on Frame 1, Audiocodes wants to receive on Port 6000 Then on Frame 28 Audiocodes re-INVITES within the same dialog but now it wants to receive on port 6002. What happens to the data that was destined to port 6000 at this point? I ask because in the context of sipxbridge, I want to know whether or not to create a second bridge for this port. Second, do I need RTCP support for fax? Thank you! Ranga -- M. Ranganathan
