[Freeswitch-users] SIP Call-ID

[Anthony Minessale]

We didn't currently support that but I added a patch to trunk that should
let you do it.

sip_outgoing_call_id variable set on a new channel should let you choose
your own call id.

on the a leg ${sip_call_id} could be passed to the b leg one of 2 ways.

using the "export" app on the A leg: one call before the bridge

<action application="export" data="sip_outgoing_call_id=${sip_call_id}"/>
<action application="bridge" data="sofia/default/foo at bar.com"/>

using the originate syntax in the bridge.

<action application="bridge"
data="{sip_outgoing_call_id=${sip_call_id}}sofia/default/foo at bar.com"/>
