[reSIProcate] [reSIProcate-commit] resiprocate 8777 sgodin: -modified the Windows implementations of determineSourceInterface to not

[maodong hu]

oh, I think I have been waiting this update for 3 years, I ever reported
this problem on 2007-7-3 as following:

Question:

I encounter register problem when my proxy server(192.168.101.28) is the
same machine that my UA running:
if I write mDum.addTransport(resip::UDP, ListenPort); then register is ok
but if I write mDum.addTransport(resip::UDP, ListenPort, V4, Data("
192.168.101.28"); then register got 503 No matching transport found

Answer:

This is because when you bind the transport to 192.168.101.28 it is binding
to your NIC only and not to the loopback address.  When sending data to the
same machine resip wants to use the loopback address.
