Hi, Could you provide the log file and packet capture? Shooting in the dark here.. It seems that you expect the response come via UDP transport, however the message might be sent via TCP (i.e: when the message is larger than MTU, by default set to 1300 bytes). If the target didn't actually listen on TCP, normally pjsip would try to re-send it using UDP. However, if the transaction timeout occurred before transport failure report received, the transaction might have got destroyed and no re-send performed. So perhaps you can try to set PJSIP_DONT_SWITCH_TO_TCP to 1, and see if the call goes fine.
