Re: [Freeswitch-users] NAT issues - Outbound Call drops after ~30 seconds

Try to catch RTP streams
tcpdump -i eth0 portrange 16384-16406
and see what happens.

Yea I know what you're talking about. That has indeed been switched off
on the RG. For reference purposes, the Residential Gateway is a 2wire AT&T-branded Uverse DSL modem/wireless router with a 4 port switch. I've also got two 8 port netgear prosafe switches. Phones and server are on the same subnet/netmask. Very simple network setup. No VLANS, etc. This was indeed working with Asterisk, so I'm almost positive it's a configuration issue with FreeSWITCH.
If there's a need to look at more than the files/logs I've pb'd, please let be know!

Both of those variables (ext-sip-ip and ext-rtp-ip) are set to the stun server, see pastebin 18699 (third link in original email).
If the (ADSL) router has a (for lack of a better term cause I can't remember) "SIP helper" app, try disabling it. Similar to the Cisco "SMTP Fixup" functionality which does an excellent job at the opposite.

I'm having the same issue. For info, I'm running static one-to-one NAT, have tried with and without STUN, and have checked the RTP ports etc. No vlans etc either. Worked fine with my other test system (3cx) so again think it must be a freeswitch config issue. - absolutely On 20 Mar 2012, at 10:32, Andrew Cassidy wrote:
