A double NAT has always been very tricky for me, I ended up merging my doubled subnet into the primary. As for your contact address, try using STUN to check your external IP in your vars.xml and external.xml http://wiki.freeswitch.org/wiki/NAT <http://wiki.freeswitch.org/wiki/NAT> On Tue, Jun 14, 2011 at 3:50 AM, Henk Oegema <henk@oegema.com> wrote:
I'm in the process of changing from Asterisk to Freeswitch (Version 1.0.head (git-0675b59 2011-06-06 21-28-14 -0500)). I have a problem with one way audio, when using Localphone.com with FS. (Audio is OK both way with localphone.com in Asterisk). (Audio is also OK bothway in FS with powervoip.com and jumblo.com)
Problem: mobile -> Localphone.com -> FS audio is OK FS -> Localphone.com -> mobile audio NOK
My setup is a little bit specific : internet -> internetmodem -> (ip:62.195.45.192) router1 -> switch ->(ip:192.1.68.1.144) router2 -> (ip:10.0.0.101) FS server Explanation of above line; router1 has external-ip:62.195.45.192 router1 gives router2 external-ip:192.1.68.1.144 router2 gives FS server internal-ip:10.0.0.101
When I connect to localphone.com with Asterisk, I see: Device name: Asterisk PBX 1.6.2.7 Status: Online Received IP address: 62.195.45.192 Contact IP address: 62.195.45.192 <----------!!
When I connect to localphone.com with FS, I see: Device name: FreeSWITCH-mod_sofia/1.0.head-git-0675b59..... Received IP address: 62.195.45.192 Contact IP address: 192.168.1.144 <-----------??
It looks to me that the one way audio has to do with the Contact IP address:192.168.1.144 (???) Is it possible to change a setting in FS so that Localphone.com will get Contact IP address: 62.195.45.192 ? (may be this solves the problem)
(I don't think (?) it has to do with port-forwarding, since all audio is ok with Asterisk)
