asterisk users - Aug 2005 - g729 recording on asterisk using g729 enabled phone

hi,

i have installed asterisk on my system and using only g729 enabled phones.
from what i understand, we would not be needing any g729 licenses as all my
voicemail prompts are also in g729 and asterisk is not doing any
transcoding. when i use the voicemail function to record, the message is not
recorded (0 byte file is created) and it gives the following errors -

"unable to convert from g729 to slin"

in my voicemail.conf, the format is set as
format=g729

and in sip.conf,
disallow=all
allow=g729
allow=ulaw
allow=alaw

the asterisk version is 1.0.5

what might be the reason ?

regards,

tulika
