I'm setting up a pbx. Incoming calls to the main number will ring on 3 "front desk" phones. If all phones are busy, I want to play a message saying:
"All operators are busy. Please call back in a few minutes or send email."
However, if the call rings for 20 seconds with no answer, it should transfer to voicemail.
My dialplan has:
<action application="set" data="continue_on_fail=true"/>
<action application="set" data="call_timeout=20"/>
<action application="bridge" data="${group_call(operator@${domain_name})}"/>
<action application="answer"/>
<action application="sleep" data="1000"/>
<action application="???"/>
The last application should be to do one thing (play a message) if the bridge failed because all phones were busy, and do something else (transfer to voicemail) if there was no answer after 20 seconds.
Is this something that can be done in the dialplan? If not, do I use a script?
