Summary: Dialog Ping

Initial Comment:
I'm having some problems with the Dialog Ping when using another port different from the 5060.
My opensips is listening on both ports, 5060 and 5062 and, as the trace attached, when the client is sending requests to the port 5062 and the dialog is created, the Dialog Ping sends the OPTIONS packet from the port 5060. Because of this, my client's NAT is blocking the packet, because its mapped to the port 5062 and not the 5060.

Follow the dialog information:

* The SIP Trace attached was made while using the Opensips 1.8.1, but I did the test with the newest 1.8.x version e the problem was the same.
