Hello,
We are trying to send a specific response code back to A-leg based on B-leg's response code.
We need to send a 503 to A-leg if B-leg returns a 480
We have the following setup in the A-leg dialplan before the bridge
...
<action application="set" data="continue_on_fail=true"/>
<action application="set" data="hangup_after_bridge=true"/>
<action application="set" data="sip_ignore_remote_cause=true"/>
<action application="set" data="proto_specific_hangup_cause=sip:503"/>
<action application="bridge" data="sofia/internal/sip:blah@blahblah.net:5060"/>
....
The b-leg returns 480 and then FS returns a 480 back to A-leg

We cannot use the respond app in this case because of how our dialplan is generated.
From what I read on confluence <action application="set" data="sip_ignore_remote_cause=true"/> and  <action application="set" data="proto_specific_hangup_cause=sip:503"/> should accomplish what i need here, but it does not seem to work.

Is this a bug or am I misunderstanding those channel variables?
Is there anyway to send a response code using channel variables (not using respond app)?

Thanks,
Emmanuel
