[Freeswitch-users] Codec enforcment from dialplan?

[Dmitry Saratsky]

Hi All,

 

I have some codec-prefs in my FS configured globally for all profiles (In my
case: "global_codec_prefs=G729,PCMU,PCMA,GSM"/>)

In addition, I need to provide for some specific incoming channels other
codec order (PCMU,PCMA) that destined to FS itself. I can identify those
channels by destination number of incoming call (fax service) in my
dialplan.

I can enforce needed codec from dialplan successfully for my outgoing
channels by using (absolute_codec_string='PCMU,PCMA'), but I'm failing to do
the same for incoming channels.

So now I'm enforcing all incoming calls from my provider to different from
global order (<param name="inbound-codec-prefs" value="PCMU,PCMA"/>),
instead of doing this for fax calls only.

 

Any ideas?
