[asterisk-users] high cpu average load

[Kamlesh Kumar]

Hello,
 
Running one asterisk server with below details. 
Only SIP to SIP calls. No real time configuration, no recording, no voicemail, no IVR, no codec translation. Average CPU load varies between 4 to 30 for 150 to 200 concurrent calls and we start getting problem in call quality like delay in connectivity, voice breakage etc....
 
Hardware: 
2 Physical processor Intel(R) Xeon(R) CPU            5120  @ 1.86GHz
8 GB RAM
500 GB Sata HDD
 
Asterisk: 1.6.2.9
PHP 5.3.3 (cli)
MySQL: 5.0.77 
Linux: CnetOS 5.5 (Final)
 
Please suggest the solution.
 
Thanks,
Kamlesh
