[OpenSIPS-Users] how to relay failure signling to FreeSwitch?

[merlin.li at tsingch.com]

Hi all,
I noticed that someone alreay asked same question, what he got is :
because it is against RFC3261 - 6xx reply means global failure and no 
further forking is allowed.

But i still want to know how others handle this situation? i mean how to play a recording to the caller when opensips received a "603"

Thanks in advanced.

Hi all, 

My opensips working with FS.
What i want is when the callee decline a call, FS will play a  recording to the caller.
Since t_relay() can not be used in onreply route, i add the following in the failure_route.

failure_route[failure] {
        if( t_check_status("603")){
            prefix("Busy_");
            t_relay("192.168.1.2:5080");
            exit;
        }
}

And i got the following error:
Mar  2 11:48:03 VS /usr/bin/opensips[38986]: ERROR:tm:t_forward_nonack: discarding fwd for a cancelled/6xx transaction
Mar  2 11:48:03 VS /usr/bin/opensips[38986]: ERROR:tm:w_t_relay: t_forward_nonack failed

Any help will be appreciated.
