Hi Julien,

there is SDP parser functionality in the core (core/parser/sdp/sdp.h), if you
need more functionality for parsing this should be probably extended there.
The sdpops module then provides SDP handling function to use in the cfg file,
using the core. Maybe it would be sufficient to use existing functionality
here, or change/add some new functions in this module.

Best regards,

Henning
