[reSIProcate] STUN Error

From: Karlsson <boost.regex@xxxxxxxxx>
Date: Sun, 13 Jan 2008 18:08:53 +0800

Hi all, I try to implement the STUN, but now I got a matter.

As I read the WIKI, I wrote some code for my UA, now the UA can be used the STUN to register to server,

but when I make a call, I got a assert error:

TransportSelector::transmit, line 587

               assert((source.getPort()==temp.getPort() ||
                       temp.getPort()==0) &&
                        source.ipVersion()==temp.ipVersion() &&
                        source.getType()==temp.getType());

The attachment is SIP message log and there are my source code, please help me to solve this problem.

Thanks
