This is actually sort of easy. You simply have every call pass through a 
context in which you assign the call to a group, then either do a NoOp 
echoing the group count or a user event doing the same, then either 
programatically or grep search your logs for the output or have a script 
monitoring the AMI watch for the user event and write the number in a 
data base.

Of these two I personally do the second option because then I can just 
do a max() function on that database field to get the maximum calls for 
any time range I specify.

Oh and just a note, never just say no because you don't know, in this 
instance you would say, "I think your best bet is the CDR's". Just a tip.
