[reSIProcate] Trouble listening on non-standard port

["Dale R. Worley" <dworley@xxxxxxxxxxx>]

I'm running into trouble with dum/resiprocate when I have it listen on a
non-5060 port.  It seems simple enough:

   dum.addTransport(resip::UDP, mUdpPort);

and when I run the code, netstat shows that my program is listening on
the port I specify.  But when an INVITE is sent to that port (and I can
see the packet via Ethereal), the onNewSession
(resip::ServerInviteSessionHandle, ...) method is not called.  But when
I set mUdpPort to 5060, everything works as expected.  Is this a known
bug and/or is there something else I need to do to get Dum to listen on
a non-standard port?
