[asterisk-users] Hardware spec comparison
All, I've a question on A*k hardware. I'm running 1.2.18 on a Dell DC051 (Intel(R) Celeron(R) CPU 2.80GHz) with 512mb RAM. I'm supporting 60 users (Cisco 7940s each + Xlite PCs).

RE: [asterisk-users] Hardware spec comparison
It could also be that network congestion is causing the quality degradation. Do you have quality of service configured on the LAN? You mention that you are IP only; does that mean you are doing local traffic only or are you connecting to the public network via your internet connection. If you are connecting outside your site, your outside connection could be saturated or having latency problems, etc. Also, you could look at memory usage as Asterisk is a memory intensive program. So there's a few more things for you to think about. Bobby -Original Message- All, I've a question on A*k hardware.

No first-hand experiences of badness with just ztdummy and that sort of call load myself though...
