Is it only external calls? And is NAT involved anywhere? 5 mins sounds like a NAT timeout. Try making an internal call and see if it drops after 5 mins. That would give you a clue if there is a firewall/NAT issue.

Subject: [Freeswitch-users] Calls ending after around 5min

I've got calls that are getting disconnected after 5 minutes (.

There's some calls that don't, and we don't have many calls that last that long (which is why we hadn't noticed until now.)

I've had a look through the documentation, and the only thing I saw that looked likely was the rtp-timeouts which I changed to this without any change:
<param name="rtp-timeout-sec" value="1800"/>

(changed in internal and external profiles)

Here's the log output for when the call ends:

Any other settings I should be looking at?
