Our company is planning to implement VoIP on top of existing cisco network and I'm conducting network audit. Can somebody advise me the resource consumption in term of CPU utilization / Buffer utilization across all platforms (26XX ... 75xx) for a single voip circuit ? My logic if my current 4700 spends 40% CPU utilization on pure data and each voice circuits (50 pps) consumes 2%, I should not put more than 10 circuits to keep cpu in the safe zone of 60%. Similar logics for buffer. The assumption of voice circuit is: VoIP, G.729r8, no VAD. If you have conducted such kind of network audit for voip implementation before, appreciate if you can share with me privately. Thanks.
