[reSIProcate] How to change port twice

[Christian_Gavin at logitech.com]

reSIProcate allows to set the port for a given transport:

                  sipStack->addTransport(UDP, port);

Is there a way to replace a transport by another one afterward (I am mostly
interested in changing the local port number) ? Or does the current
implementation require for a user to change port to restart the application
?

Thanks!
