[cisco-voip] DSP configuration

[Syed Khalid Ali]

*Micah,

I have two links that can help you:
DSP Calculator: http://www.cisco.com/cgi-bin/Support/DSP/cisco_prodsel.pl

AND

PVDM2 data sheet:
http://www.cisco.com/en/US/prod/collateral/routers/ps5854/product_data_sheet0900aecd8016e845.html

One more thing, total session are calculated on the basis of voice channels
required by each codec. but how do they calculate the number of conferencee
per session.

Any thought on that from the experts on this list!
