Hi Ricardo,

Yes, media may be there, I am just worried about backwards compatibility
since nobody had complained about it before and I wonder if there is PBX's
out there which do not generate early media. Although, second thought, if
that is the proper behavior I'd rather have users move away from the old
wrong behaviour.

The FreeSWITCH bug has been fixed. Thanks for reporting it. We just did a
bunch of new changes to the FreeSWITCH R2 module, all the feedback is
appreciated.
