[OpenSIPS-Users] t_relay and forward accepts only literals

[Liviu Chircu]

That's because I just copy-pasted your example and adapted it without 
thinking. It should be:

force_send_socket(sctp:10.12.8.108:5060 <http://10.12.8.108:5060>)
$ru = "sip:" + $od + ":" + $op + ";transport=sctp";
forward();
