[asterisk-users] call from h323 to SIP

[Pavel Jezek]

probably you haven't g729 installed in asterisk, use g711 instead, put 
this in h323.conf and in callmanager place asterisdk gateway in region 
that will use g711...
disallow=all
allow=alaw

alternatively you can find g729 codecs binaries here:
