[reSIProcate] Adding STUN support

["Matthias Moetje - TERASENS GmbH" <moetje@xxxxxxxxxxxx>]

Hi,

I'm currently trying to implement STUN support using 
the StunTest function in stun.cxx

- when I do StunTest I need to know the local port and IP
  address that will be used by resiprocate to send out a
  sip message

- Currently I check userprofile::getFixedTransportInterface()
  to see if a fixed local IP address is used, otherwise I call
  SipStack::getHostAddress to get the default address.

But how can I know the local port resiprocate will use to send the
message before the message is actually sent?


After StunTest has completed, am I right in calling
userprofile::setOverrideHostAndPort to set the external
IP address and port detected by STUN?


Thanks very much for your help 
and best regards,
