Hi, I have troubles with CUPC (7.0) connecting to CUCM (6.1) and passing third-party FW (CheckPoint NGX R65).
CUPC starts SIP connection on UDP:
SRC port: 50000
DST port: 5060
Does anybody know, if it is possible to configure CUPC, that it will start connection from SRC port 5060 too?
CP support claims that SRC port 50000 it is not by RFC SIP standard and they can not easy change FW kernel inspection behaviour. Thank you for all answers,Andrej
