[Freeswitch-users] mod_sms chat messages delivery notification

[Marko Djuric]

Hi all,

We're using mod_sms for SIP SIMPLE messaging with delivery notifications
(message/imdn+xml).
The Call-ID is changed in the chatplan, and this causes issues with matching
the delivery notifications to the original message.

Changing the Call-ID itself is not an issue, but I'm wondering if it is
possible to read the original Call-ID and/or manually set the Call-ID in the
chatplan.

The message:getHeader("sip_call_id") does not contain the Call-ID. My
understanding is that this is due to skip_global_process=false variable set
by mod_sms.
Setting the sip_call_id variable also does not produce a desired effect, as
it is added as another header instead of setting the Call-ID one.

The question is - how to match the messages before and after the chatplan? 

Any help is appreciated.

Thank you!
Marko
