Summary:                    With Digium transcoder card G.723 conversations
involving prompts from Asterisk are still not possible
Description: 
I am having a large installerbase of Linksys PAP2 which use 2 channels and
therefore are restricted to G723. Apparently the PAP2T can handle G723
5.3kb like the Digium transcoder card, but when I dial voicemail I can
barely make up what it is saying, the voice coming from Asterisk is
garbled, although set to G723.

All is working fine in 1.2.x ... But I want to have the additional
features and fixes of 1.4.x to enhance my business...

Even with no codec card and using the g723 sound files, the result is
still garbled sound in 1.4.x, again, voice is clear in 1.2.x

Is this a problem in Asterisk core or Digium transcoder card?

Hi, this is not an issue with the sound prompts... I put the g723 prompts
in to prevent it failing because of no transcoder available... Here is what
I have tried so far:

Asterisk-1.2.19 - software codec g.723  (intel derivative): OK
Asterisk-1.2.19 - TC400B hardware card: *Very* bad quality (like talking
through 2 tin cans with a rope), and errors on the asterisk console - even
after hangup.

Asterisk-1.4.4 - software codec h.723 (intel derivative): NOT OK, garbled
sound
Asterisk-1.4.4 - hardware codec: Same result - NOT OK, garbled sound.

So this seems to be a combination of 2 problems...

I bought the hardware codec card so I can switch to 1.4.x and yet service
my G723 codec customers, however I can forget the card altogether until it
supports G723.1 6.3k

Asterisk 1.4.x, with or without the hardware codec card does NOT support
G723 anymore, in any bitrate... Hope somebody can look at this.
