hello, i wanted to use g729 in asterisk (iax to sip) as passthrough. Has anyone got experience with configuring this or does someone know if this is possible at all? At the moment asterisk2 is always transcoding to alaw but but this results in horrible voice quality. phone1 behind NAT (sip) -> SER -> asterisk1 (iax) -> asterisk2 -> phone2 thanks for your help pamela
