Let me understand first: the SIP phone doing the recording is not one of the people on the conference? It's in monitor mode, for recording purposes only? If that's the case, then you can't achieve audio quality higher than the individual conference node channels themselves -- sort of a 'lowest common denominator' situation. If you could get all nodes using a wideband codec (say G722), and if Asterisk supports wideband mixing and recording (i.e. everything done at 16 kHz sampling rate), then you might be able to do it. -Jeff -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
