[Asterisk-Users] One SIP peer use 2 diff codecs?

[Race Vanderdecken]

Here, here,

I agree. Each channel should be able to decide which codec to try first.
This will cause more call setup messages.

1. Hi, do you have GSM?
	No

2. Hi again, do you have G.723
	No, go Fish.

3. Hmmm, do you have (cringe) G.729?
	Yes, do you have License for your Minkey?


My understanding of SIP is that the caller suggests, the callee replies
with their preference(s).

So the call setup is a little more complicated but not that hard to do,
just need some routing logic on the caller side. Sort of the way a
gatekeeper decides where to route a call.

perhaps tha should be changed, then, to allow more control over codec 
handling?
