[OpenSIPS-Users] how to implement call forward after 486 (busy) with 181 message

[Brett Nemeroff]

Well what you've posted will just redirect the call.. you'd never know it
was redirected really.

If you want you can send a:
sl_send_reply("181","Call Is Being Forwarded")
before you t_relay.. i think that will work.. Let us know..
