There should now be a SIP/VoIP section on this forum, so not sure exactly where to post this. I have tried to use the g729a codec w/Asterisk and my E61 over both WLAN & GPRS. The results were almost unuseable voice quality. While iLBC, w/Asterisk, seems to provide pretty good quality. And as for G711/alaw, I have not manged to force the use of this codec, as when I try to limit on the Asterisk side I just get 'no supported codec available' when I try to connect the E61.

Is there a plan to improve the g729a support to something useable? Also, how about forcing the codec used on the E61 side via the configuration?
