[Asterisk-Users] G729, voicemail, no codec_g729

[Kristian Kielhofner]

	I am trying to create a %100 g729 (with no transcoding) system (using a 
Soekris, of course).  I am running AstLinux with the native sounds, g729 
is the only codec allowed, %100 SIP (g729 only allow=) - I think I am 
covering all of my bases.

	I have only "format=g729" in voicemail.conf.  On an incoming call to a 
mailbox, everything goes well until recording the message.  When the 
message is supposed to be recorded, the voicemail app bombs and this is 
displayed on the console:

     -- Recording the message
     -- x=0, open writing: 
/var/spool/asterisk/voicemail/default/105/INBOX/msg0001 format: g729, 
0x8140f88
Jun  1 10:08:45 WARNING[15148]: channel.c:2326 set_format: Unable to 
find a codec translation path from g729 to slin
Jun  1 10:08:45 WARNING[15148]: app.c:621 ast_play_and_record: Unable to 
set to linear mode, giving up

	Obviously I don't have codec_g729 installed.  The real question is, why 
does it need to convert to slinear?

Thanks!
