Re: [Freeswitch-users] Call exits after 120 seconds with hangup cause

I think the problem is the session-timeout is too long and your nat mapping is being deleted.

we changed the param session-timeout (in internal) to 20 and 40, without success. we changed the minimum-session-expires to 20, although we knew, the allowed minimum is 90 and 90 was shown in the console - no success.

try setting it to a smaller value like 20 or 40 sec or try setting those phones to register more frequently (every 10 or 20 sec)

we changed all possible options to 10 and 20, again without success :(
