Is there any difference in your POTS line vs. cell quality? As you may know, cell phones typically use some type of voice codec (GSM-AMR, EVRC, etc) that can reduce quality of non-speech audio (e.g. music). But the POTS line should sound fine, unless you sent it first through a carrier IP route using compression (such as G729). -Jeff -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
