Calling on VoIP Customers - Call Volume Question

In preparation for the next major VoIP release, I am polling our customers to determine our typical customer's call volume.  It would be very helpful if you could provide me answers to the following quetions:

  1. How many calls per minute do you average on a typical day?
  2. How many calls per hour do you typically average on a typical day?
  3. Do you have a need to monitor average call duration for a given timeframe?
    1. How many calls per minute do you average on a typical day?
    2. How many calls per hour do you typically average on a typical day?
    3. Do you have a need to monitor average call duration for a given timeframe?

    Ill take our corporate office Callmanager cluster as an example. We have 950 phones and aveage 1800 calls a day OnNet (internatl) and 450 outbound calls daily.

    Inbound calls we average 600 inbound calls and per hour we average 200@hour for outbound

    average call duration for us isnt as important as flagging long calls, and quick hangups
