[asterisk-users] Troubleshooting load issues

All the calls are using ulaw. The files that I am playing are gsm. I
suppose doing a file convert with sox to .ulaw may help but it should be
able to do 500 calls without an issue. Can it possibly be a bug? if not how
do I profile which call(s) can be causing the spike?
