Done that already: but then, the "incoming channel" (from the user to Asterisk) is G729, and the "outgoing channel" (from Asterisk to the PSTN gateway) still remains ULAW, so Asterisk has to do transcoding (ULAW to G729), which I don't want, obviously.

For some reason, the outgoing channel doesn't follow the setvar(SIP_CODEC=g729) rule.
