[Freeswitch-dev] SIP INFO carrying MSML

[Owen Williams]

Hi all,

I'm looking into the possibility of getting basic msml support into
freeswitch.  We have a few applications hosted on a remote SIP Application
server that already use MSML against another media server.  The application
acts as a back2back between a caller and the media server and sends info
messages (inside an invite dialog) to the media server with the INFO sdp
containing MSML (e.g. play file, join conf, etc).

I'm a bit new to freeswitch but I'm guessing mod_sofia would need to
modified to send info events to a new module or to the ESL, and mod_sofia
also needs to be capable of receiving events to send INFOs back to the
remote B2B.

There was a bounty completed about 18 months ago (Generate and be notified
of SIP INFO messages) however this may have been only for out of dialog
INFOs.

Any information as to whether the above bounty made it into trunk and how it
can be enabled would be appreciated.  I'd like to have a play with writing a
MSML processor through ESL as I've far more experience with ESL than writing
c modules.

Regards,

Owen
