[Freeswitch-users] Codec enforcment from dialplan?

[Steven Ayre]

The default behaviour is to select the codec for an incoming call *before*
it hits the dialplan.

To work around that you should enable late-negotiation on the sofia profile
taking the incoming call. That'll delay selecting a codec until media starts
for a bridge. The codec will then match the bleg if possible, and otherwise
will pick the preferred codec from your lists. The alternative would be to
have multiple profiles with different codec preferences on each.
