Hi Steven,

The original location of this is:

   http://karlsbakk.net/asterisk/scripts/asterisk-mrtg

The down-side is that mrtg only samples every 5 minutes, and as there is 
no running total, just an instantaneous count in gauge mode, it has the 
opportunity to miss calls made when it's not sampling. So this is OK for 
busy sites where a few calls either way won't be noticed, but I'm dealing 
with relatively low call volumes of 1-2 a minute, with very occasional 
bursts to (maybe, I don't know yet!) 4-6 simultaneous calls.

(I have a customer who has 4 ISDN2e ports; 8 channels) and they want to 
know if they can lose one port and save some money)

I'm working on something slightly better that will poll it more often, but 
still provide an mrtg interface. I'll post details here, but it's not that 
high a priority right now.

Cheers,

Gordon
