[Freeswitch-users] Retrieve active call from voicemail

[Dean Coulter]

Thanks Avi,

I have it working using the UUID.  Just before the call diverts to VM it 
inserts a hash.  The user can then dial # to retrieve(intercept) the 
call from the VM system.  The VM loopback hangsup at the time the call 
is intercepted.  Note that in this instance, any extension can retrieve 
the call by dialling # (this is the main number which rings on all phones).



<extension name="inbound_calls">
<condition field="destination_number" expression="^(200)$">
<action application="set" data="ringback=${au-ring}"/>
<action application="set" data="call_timeout=25"/>
<action application="set" data="hangup_after_bridge=true"/>
<action application="set" data="continue_on_fail=true"/>
<action application="bridge"
                         
data="{ignore_early_media=true}sofia/internal/302%${domain_name},sofia/internal/301%${domain_name}"/>
<action application="answer"/>
<action application="sleep" data="1000"/>
<action application="hash" 
data="insert/${domain_name}-retrieve_vm/global/${uuid}"/>
<action application="bridge" data="loopback/app=voicemail:default 
${domain_name} 301"/>
</condition>
</extension>





<extension name="retrieve-vm">
<condition field="destination_number" expression="^(\#)$">
<action application="intercept" 
data="${hash(select/${domain_name}-retrieve_vm/global/${uuid}"/>
<action application="answer"/>
<action application="sleep" data="1000"/>
</condition>
</extension>
