[Freeswitch-users] Intercom

[Brian West]

The Alert-Info header you posted is invalid, But that looks like  
you're doing it for Polycom for what I can tell.  sip_auto_answer=true  
Already covers the polycom auto answer case.

     <extension name="extension-intercom">
       <!-- <condition field="${sip_to_params}" expression="intercom 
\=true"/> -->
       <condition field="destination_number" expression="^8(10[01] 
[0-9])$">
         <action application="set" data="dialed_ext=$1"/>
         <action application="export"><![CDATA[alert_info=<sip:$$ 
{domain}>;Ring;Answer]]></action>
         <action application="export"><![CDATA[sip_h_Call-Info=<sip:$$ 
{domain}>;answer-after=0]]></action>
         <action application="export"  
data="sip_invite_params=intercom=true"/>
         <action application="export" data="sip_auto_answer=true"/>
         <action application="bridge" data="user/${dialed_ext}@$$ 
{domain}"/>
       </condition>
     </extension>
