[asterisk-users] Peak number of calls?

[Gordon Henderson]

Is there any way to find-out the peak number of calls that an asterisk 
system has had? Not the total number of calls, but the maximum number of 
simultaneous calls.

I know I can porobably go through the CDR logs and look for calls which 
have overlapped in time, but I'm wondering if there's some counter 
somewhere I could access...

(I'm looking for evidence for an ISDN client who wants to know if he's 
spent too much on the number of ISDN lines he has installed!)

Cheers,

Gordon
