We are looking at a customer that is converting to VoIP. They will have about 7K phones with about 14 PRIs. My first question is there a better way to set up a bunch of conference bridges besides loading up gateways with a bunch of DSPs? My second question is where I can find a better DSP calculator that I can specify number of conference bridges and PRIs and is updated with the new 2900 and 3900 series routers? Does anyone have a custom excel sheet I can use? Any help/insight in this would be great.
