[Freeswitch-users] Call dropping after 32 seconds

Mon Feb 29 22:27:30 MSK 2016

Hi Rutu,

Firewall should not be an issue. If you think that it may change SIP
packets, you can always use TLS. I doubt that it is good idea to add one
more server in set-up, just because of firewall, you just need to configure
all of your servers, devices properly.

If you can, you should eliminate unnecessary servers from your set-up.

>From what you described before, it might be issue not connected to NAT, but
because Opensips wasn't configured properly. I had similar issue when
Kamailio(Opensip is fork from Kamailio project, so they almost identical)
was wrongly configured, particularly path header wasn't inserted by
Kamailio. But this 30 seconds timeout is quite often NAT issue, but again
if you have NAT issue, you should not blame FW or anything else, you should
just configure your Freeswitch and Opensips properly. Almost all devices in
internet are behind NAT and almost all of them works perfectly with VoIP.

So if you need, help, then please send full sip trace, so I can take a look
on it.

With kind regards,

Jurijs
