Just discovered another weirdness. Test case: openpbx connecting to Cisco Gateway to send a fax. Initially they exchange ports for RTP (port A for openpbx and port B for Cisco). After some "agreements" they decide to use T38 on udptl. And it is correct. So Openpbx allocates port C for UDPTL and Cisco reuses port B. Nothing wrong here. SIP messages are formatted correctly. The problem is that Cisco assumes that openpbx is reusing his RTP port for UDPTL too, so it sends UDPTL packets on the RTP port which complains about them beeing too short, even if openpbx told Cisco to use another port. I do not know corelib/chan_sip very well. Does anyone has some idea on how to hack this ?
