[Freeswitch-users] internal & external ip addresses of freeswitch

[Timur Irmatov]

Hi.

We have a local network 192.168.1.0/24, where all the users are. Out
FreeSWITCH server is connected to this network, and has ip address
192.168.1.242. Through different network card it is connected to
external gateway, and has address 172.16.12.11 in this network.

I set up a test client with softphone. When incoming call is
deliviered to this client, call is set up normally, but client can't
hang it up. It sends BYE to external address - 172.16.12.11 - which is
not reachable from the client. It seems this address is coming from
Contact: field in INVITE that FreeSWITCH sends:

U 192.168.1.242:5060 -> 192.168.1.34:37169

What should I tweak in freeswitch to change this behaviour?
