Hello,
i have a problem with one PBX (SI3000) using outgoing call (HMP SU 361). The external outgoing call is made normally and audio files are played properly. With the internal PBX call the situation is different - the call is connected, Dialogic plays the file but on the other end nothing is heard. As far as I understand the PBX in SIP "ringing" message indicates the new destination IP address but Dialogic didn't react. How to solve this issue?
Wireshark log files (zipped) with good and bad call are attached
