If you can ensure that voice traffic has top priority in all the routers between the two sites, there should be no difference in voice quality. For a true point-to-point system this is trivial to achieve, and maximizes the bang-for-buck ratio of your interoffice connection. Obviously having two ADSL connections is not true "point to point" -- you will want a leased line, or a dedicated connection to a common provider who has the prioritization of voice traffic in your SLA. You could, in theory, have higher than telco quality voice calls with a VOIP system, as you are no longer restricted to 8kHz-sampled, 16-bit audio. Naturally the phones must support this for this to work. > What configuration areas are there to be set and how are they diffent than > just a standard PRI, which I have working now? If you put a point-to-point DS1 between sites, it's easy. Asterisk can act as a PRI CPE or CO endpoint. -A. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
