[Freeswitch-users] absolute_codec_string question

The problem is that FS splits the variable names using commas. When there's
a comma in a value it gets confused. Using quotation marks doesn't make any
difference - they're treated as part of the value.

So FS is seeing this:
ignore_early_media
absolute_codec_string='G729
PCMU'

So the only codec that gets set is the G729.

There is a workaround for this. You want to use
{ignore_early_media,absolute_codec_string=^^:G729:PCMU}.

The ^^ at the start of a value tells FS 'treat the following character as a
comma'. Now FS sees:

ignore_early_media
absolute_codec_string=^^:G729:PCMU

And sets absolute_codec_string to G729,PCMU.
