Hi Gabriel,
Thanks for your answer

so to summarize, I should (I did tome tries)

1) kind of park if failure - kind of replace the voicemail

       <action application="bridge" data="user/${user_data(${destination_number}@${domain_name} attr id)}@${domain_name}" />
       <action application="answer" />
       <action application="park"/>
       <!--<action application="sleep" data="1000" />
       <action application="voicemail" data="default ${domain_name} ${dialed_extension}" />-->

2) subscribe to "event xml CHANNEL_PARK"

Then I can get
<Core-UUID>7e4fd02a-b260-11e1-9687-c13084909128</Core-UUID>
<variable_dialed_user>1234</variable_dialed_user> (there the extension my dialplan initially transfered the call to)
<Unique-ID>43cca2b4-b311-11e1-a4d1-c13084909128</Unique-ID>
<Channel-Call-UUID>43cca2b4-b311-11e1-a4d1-c13084909128</Channel-Call-UUID>

==> which UDID is the one I should watch to be able to unpark the call ?

==> which command from mod_command should I then use to "resume" the call ? or transfer/bridge again to extension 1234

Regards,

John

What if you used your dialplan to try to call the phone and if you do
NOT find it, park the call. Then you might use the event socket to
watch for the parking of the call so you can send your notification.
Next, use the event socket to watch for sofia registrations to know
when the app has received the notification, launched and is ready to
take calls. Once you get that event, unpark the call and send it on
its way.


Best,
Gabe

P.S. go python!
