My VoIP provider uses G729 as one of their codecs.
My soft phone has G729 as the only codec in use.
My soft phone that keeps a conference open with my Asterisk box and lives in that channel for the duration of the call.
Calls are then dialed on the Asterisk box and if they are successful, connected to the conference that my soft phone lives in.
Is there any use of transcoding in this situation?
Not also that the only selected codec in the soft phone is G729.
Does pass thru come into play here?
