*
* \par incoming packets
* Incoming packets are received in the monitoring thread, then handled by
* sipsock_read(). This function parses the packet and matches an existing
* sipsock_read() for udp only. In tcp, packets are read by the tcp_helper thread.
* sipsock_read() function parses the packet and matches an existing
* dialog or starts a new SIP dialog.
*
* sipsock_read sends the packet to handle_incoming(), that parses a bit more.
