Except if the UAC uses two different UDP sockets, which I think is
quite common in implementations, one for sending UDP (with connect())
and another for receiving UDP datagram on port 5060. And because the
UAS will send the response to the addr/port specified in the topmost
Via, not to the source addr of the packet, the response will go to the
port 5060 in the UAC, which will be (happily?) received by the
receiving socket.
