In that case if you still want to have g729 go across the wan you'd need to be transcoding to 711 at the central site, not at the remote site gateway.<div><br></div><div>As far as the dial-peer goes I'd recommend a codec class with all the variants of 729 (that don't have 'b' in them) to prevent potential failures because of variations in codec support across your devices or other gateways. You don't want to use g729b because it includes voice activity detection (vad) and will cause even poorer voice quality than you'll be getting with 729.</div><div><br><div apple-content-edited="true">
