asterisk users - Apr 2007 - G.729 Pass-Thru & Voicemail

Hello, 

I have just updated my Asterisk installation from 1.2x to 1.4 (on
FreeBSD) - mostly everything seem to work fine.

However, I use G.729 pass-thru - and I have before successfully used the
following setup:

However, it is not working with 1.4 - I see the following errors:

[Apr 16 15:59:24] WARNING[10139]: channel.c:2816 set_format: Unable to
find a codec translation path from g729 to gsm
[Apr 16 15:59:24] WARNING[10139]: file.c:804 ast_streamfile: Unable to
open vm-login (format 0x100 (g729)): No such file or directory
[Apr 16 15:59:24] WARNING[10139]: app_voicemail.c:6104 vm_authenticate:
Couldn't stream login file


Is there any way I can get the voicemail functionality back, without
reverting to gsm?

Also - anyone know when native G.729 codec will be available for 1.4 on
FreeBSD?

Many thanks,

Mike
