Hi

I a using ser with rtpproxy.. i am using stable version from cvs ... my scenerio is :

public ip(xlite phone) Client A | | | SER Server (public IP) | | | | Private IP (xlite phone) Client B

I am able to call from B to A. But unable to call when try to place call from public tp private.. The softphone displays error: "Response 479:We don't forward to private IP addresses" plz help me in this scenerio.

my config file is: # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script #
