Hi, I need to generate a "content-type: Multipart" Body and add two additional content parts to an INVITE on the B-LEG (bridge). Is this currently supported ? I found there is the variable sip_multipart. If I set something in this var the outbound INVITE is MULTIPART. How can I add two additional parts to the body ? Tried some wired stuff such as: <condition field="${Username}" expression="^([5])$"> <action application="export"><![CDATA[sip_multipart[0]=application/pidf+xml]]></action> <action application="export"><![CDATA[sip_multipart[1]=test]]></action> <action application="export"><![CDATA[sip_mp_application/pidf+xml=testdata]]></action> <action application="info"></action> </condition> How to add this body parts ?
