We’re having a bit of a strange issue with our 3300 and I was hoping someone in this forum could help us out...
Interconnects: 100% SIP
Outbound Trunk = SIP (Airband)
SIP Trunk 2 = Rightfax T.38
Basically, we’ve set Rightfax T.38 up on a SIP Trunk and inbound faxing works great. Oubound is a different story and I’m a bit stumped. All calls originating from Rightfax trigger a “503 Service Unavailable” from the 3300.
I’m including screenshots of the packet cap and the four packets of note.
Please let me know your thoughts.
Regards,
-Patrick
