[asterisk-dev] New codec support in Asterisk 10

[Jason Parker]

In Asterisk 10, we've changed the way codecs are defined, to expand the number
of codecs that we can support.  However, due to protocol limitations, many
channel drivers (pretty much everything but chan_sip) can only support a limited
number of codecs.  As an example, chan_iax2 uses a 32-bit bitfield on the wire,
which means the codec list on each side can never change.

As it stands now, chan_iax2 will silently ignore allow=silk24 in iax2.conf.
This issue has probably always existed in other channel drivers.  chan_skinny
currently only supports 7 codecs; other codecs are ignored.


How do we want to handle this?
