Hi All,

For interoperability reasons I need to re-write the From URI Domain ($fd) in requests proxied by Kamailio to the source IP (socket) that Kamailio will send them via. 

I have experimented with onsend_route and can successfully discover the snd_ip, however it seems I am unable to rewrite the $fd, presumably because I am too late in the logic.

Is this possible? I can hardcode IPs if required but would rather keep it dynamic if I can.

Thanks in advance,

Matthew
