[Asterisk-Users] IAX2: Don't know any of 0xf800 formats

[Ryan Courtnage]

Hi all,

I'm finding with Asterisk 1.2.1 (and 1.2.0) that when connecting over an
unauthenticated IAX2 connection (ie: as [guest] in iax.conf), a codec
will always fail to be negotiated (see trace snippet below).

The problem appears to be specific to only unauthenticated IAX2
connections.  Authenticated connections negotiate the codec just fine.

Here's the trace.  Notice that the IAX2 Rx has a codec pref of gsm.  The
Asterisk 1.2.1 server console says "Don't know any of 0xf800
formats" ... looks like a bug to me.
