[Asterisk-Dev] Per-call codec preference

[Michael Giagnocavo]

Hi there,

	I'm thinking of adding patches to allow per-call codec negotiation,
so that the codec can be set via the dialplan ("at runtime"), instead of
just when defining peers ("design time").

	My idea would be to add a channel variable that could be a codec
("g729", "ulaw", etc.), "current", to mean whatever codec is currently in
use, or null/"default", for whatever would normally work.

	Any comments or suggestions on this?
