Summary:                    Distorted playback of G.722 prompts
Description: 
With the changes in r106501, G.722 audio FROM a Polycom 650 now works
properly; it can be recorded, transcoded, etc. without impairment.

Unfortunately, playback of G.722 audio TO a Polycom 650 is now distorted;
it plays choppily at half speed. G.722 voicemail prompts, Playback() of a
.g722 file, and G.722 MOH exhibit this distortion, as does a call being
transcoded from GSM (the Polycom -> GSM direction sounds fine).

Playback of other file formats (uLaw, slin) sounds fine, as does a call
being transcoded from uLaw.

I'm having problems as well... Polycom 650 talking to latest 1.6.0 branch
from SVN.  My sip.conf section is configured as:

[asterisk]
type=friend
secret=asterisk
host=dynamic
disallow=all
allow=g722
allow=ulaw
allow=gsm
context=g722demo
qualify=yes

and my dialplan looks like:

[g722demo]
exten => 123,1,Answer(200)
exten => 123,n,Playback(hello-world)
exten => 123,n,Playback(asterisk-friend)
exten => 123,n,DumpChan()
exten => 123,n,Playback(pbx-transfer)
exten => 123,n,Wait(30)
exten => 123,n,Hangup()

exten => 111,1,Answer(200)
exten => 111,n,MusicOnHold()

I'll attach the packet capture from tcpdump as well.
