I'm running an E100P (only 1 E1) in PIII 850, the last Friday I was sent 30 simultaneous calls, 5 seconds each call, using mysql to store cdrs. These calls was generated by an Ameritec AM2, and routed thru our Siemens EWSD. The vmstat shows that CPU was near to 20% idle with 30 ISDN Setups incoming.
PII 400? E400P? Man, you gonna fry your CPU...

I had a few problems too with a similar setup (although no machine lockups) * You are running quite a slow machine to run this script on many lines at once - I found that I needed a P4, 2.4GHz to keep up with 120 channels simultaneously (I had one system to send and one to receive, and very short calls - 3 seconds). How many instances are you running? Are you doing mySQL call logging? * I found that I could only initiate about 18 calls at exactly the same moment without getting failed outbound call errors from asterisk, so I ended up staggering the start times a little. * With lots of new calls, I had tons of framing errors on the receiving end (and occasional D channel restarts) when routing calls through my DMS100 switch - do you have problems like this? I think this problem is specific to the Nortel switch however. Suggest starting with -vvvvc and routing all output to a log file...?? regards Scott Scott M. Stingel Emerging Voice Technology Inc.
