Cisco provides a DSP calculator that provides the number of DSP chips you need to purchase based on the voice network you are supporting. You can find this tool at http://www.cisco.com/web/applicat/dsprecal/index.html (Cisco.com login required). Keep in mind that a growing network will always require more DSP resources. It is usually best to pack the router full with as many DSP resources as you can fit in it; you’re going to need them!
