One thing you can do is to ditch the fcntl() calls and instead use MSG_DONTWAIT as the last argument to recv(). I don't know if the option is portable though.

> The res_stun_monitor module monitors the perceived external ip/port provided by a STUN server and sends out an event when that perceived ip/port changes in any way.  This patch adds chan_sip and chan_iax as listeners to this event.  Both of these channel drivers react to the event by regenerating all outbound registers in order to alert the endpoints being registered with to the new address location.  This feature's primary use case is when Asterisk is behind a NAT in which the external ip address is dynamic or the port mappings of the NAT device are subject to change.
