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?

Query the sip_dialogs database table to see if all are on calls.

Steven,

You can check the originate_disposition variable to get the result of
the bridge, then based on that run the voicemail app or play the
message. It is possible to do this in the dialplan, something like:
<condition field="${originate_disposition}" data="USER_BUSY">
<action application="say" ..
<anti-action application="voicemail" ...

but I find any logic even slightly more complex than 'if this do that'
in the XML is unreadable because of having to worry about
require-nested, break and inline and reach for the lua:
if session:ready() then
originate_disposition = session:getVariable("originate_disposition")
if originate_disposition == 'USER_BUSY' then
play message
else if originate_disposition == 'ALLOTTED_TIMEOUT' then
do voicemail
else
session:consoleLog("INFO", "unhandled disposition" ..
tostring(originate_disposition) .. "\n")
.. do something sensible (like voicemail)
end

As I understand the XML dialplan, when a matching condition is found, it builds up a list of actions and executes them in order.
So I assume my list of actions would be to bridge to the phones, then transfer to another extension which would look at the ${originate_dispostion}:


Like:
... Set timeouts ...
  <action application="bridge" data="${group_call(operator@${domain_name})}"/>
  <action application="transfer" data="front_desk_no_answer">
</extension>


<extension name="front_desk_no_answer">
  <condition field="destination_number" expression="^front_desk_no_answer$"/>
    <action application="answer"/>
    <action application="sleep" data="500"/>
  <condition field="${originate_disposition}" data="USER_BUSY">
      <action application="say" ..
      <anti-action application="voicemail" ...

  </condition>
</extension>


Does that look like what I need?
