I thought I've seen this request go out before and just wanted to let
people who were looking for it know that I've got a solution. It's an
ugly one, but it does work.
Here's how it goes.
Go to CAR
Device-Reports -> Gateway -> Detail
Export the data you're looking for to a CSV.
In Excel, strip out everything you don't need until your columns look
like this:
Column A: Date
Column B: Start Time
Column C: End Time
Then, in Column E, starting in Row 2, put in the minutes of the day in
number (I use Decimal 10) format. It should look like this:
0.0000000000
0.0006944444
0.0013888889
0.0020833333
0.0027777778
0.0034722222
0.0041666667
0.0048611111
0.0055555556
0.0062500000
0.0069444444
0.0076388889
0.0083333333
0.0090277778
0.0097222222
0.0104166667
0.0111111111
0.0118055556
0.0125000000
0.0131944444
Expand that down all the way until it reaches 1.
In Column E, Row 1, enter the date you want to study.
In Column F, put this function:
=SUMPRODUCT((A$1:A$10000=E$1)*(B$1:B$100
00<=E2+1/1440)*(C$1:C$10000>=E2+
1/1440))
That will analyze the first 10,000 calls for the day you put in E1.
In Column G, I put =MAX(F2:F1441) to give me the max concurrent calls
for the day.
Management really likes this information because it gives them a good
idea if they need to buy more PRIs or cancel some.
The analysis is not perfect. It only analyzes by minute so it can miss
some connections, but it is pretty good. Usually good enough. If you
wanted to take it out to the second, it wouldn't be that difficult
either.
I have plans to create a php or PERL script that will perform better
analysis but this is what I have for now.
Hope that helps!

Something that might be of use to you; Arezqui Bela=EFd has written an
excellent call detail reporting system for use with the Asterisk PBX:
http://www.areski.net/asterisk-stat-v2/about.php?s=3D0
Included is the ability to report on "max load". Example here:
http://www.areski.net/asterisk-stat...creenshot05.png
This system uses the start and end times of each call to determine load
and therefore is not reliant on any given time interval for reporting
meaning it shows the true load no matter how short the calls are.
I would suggest they easiest way to get the reporting you want would be
to write a small PERL script which takes your existing call detail
records and inserts them into a mysql database in the same format
Asterisk uses.

Thank You..... I'm going to cancel a PRI. Wish I would have had this a
year ago. PRI's aren't cheap.

PS. Something so easy and cisco can't do it? Switch packets by the
millions but can't write a simple ASP. Cisco, are you listening. The
works done you just need to make the ASP. :-)

Under CAR > Device Reports > Gateway Utilization, I've created graphical rep
orts of the gateways that tell me how often they are used.
It doesn't provide those fancy numbers required for erlang and busy time of
day calculations, but it does show when a PRI isn't being used at all and ho
w often a PRI is used.

I extended your calculations to see peak usage by second, and after a
*very* long time Excel finally kicked out some numbers. For the most
part, it looks like the "by minute" peaks where 0-2 calls below the "by
second" peaks per PRI per day.
Thanks for the formulas though. Time to put a spreadsheet together that
does a 10-day rolling peak usage.

If they are all on trunks between CM you can monitor the trunks. Device
Reports -> Gateways -> Details -> H323 Gateways. Otherwise there might be
a gateway type listed there that you can use. If there are no gateways
between sites, you might be out of luck or have to use CDRs based on
extensions.
