[Freeswitch-users] Codec negotiation, again

[Steven Ayre]

In default behaviour, FS will negotiate the codec for the aleg, then do the dialplan, then do the bleg. As a result it can have already picked the 729 codec by the time it hits the dialplan. With transcoding that's fine but with 729 not.

The workaround is the late-negotiation profile parameter. It delays picking the aleg codec until the bleg picks one, then uses that if possible for the aleg.
