i set up freeswitch, and almost all configs are default (i made some little changes in directory and dialplan). I can call anywhere, for example to my cell phone, but call longs approximetely only 5 sec... In siptrace i found nothing. No timeouts like call_timeout or leg_timeout.

Also i thought maybe the reason in the gateway registerations...
Server has private (static) ip.
