Hi,
Could you be more specific in what the "fail to make calls" means ?
Thanks,

Hi,
I am trying to setup a OpenSIP server which should act as a SIP
register as well as a SIP proxy server.
If the server is placed in the same LAN where multiple SIP enabled
devices (e.g Cisco SX20, Polycom RPG500) reside, then the devices get
registered easily and can make SIP calls among themselves.
But everything fails when the devices are on the other side of the
internet and the server is behind firewall like following diagram.

192.168.v.w(LAN) 192.168.v.1 : 63.45.x.y (WAN) 220.54.w.y:
192.168.x.1 (LAN) 192.168.x.y
The server’s private IP (192.168.x.y ) is mapped to a fixed public IP
(220.54.w.y) and ‘opensips.cfg’ file has been prepared same as
described in the link
http://opensips-open-sip-server.1449251.n2.nabble.com/OpenSIPS-Server-behind-a-NAT-firewall-td5853352.html.
This time I am able to register the device but fails to make SIP call.
Regards,
Priyanko
