Hi All,

I am replying to my last email. Apologies if this cause any problems. 

Please see the Disk performance below. Looks to me there is no issue on the Disk IO.

Right now I am using CentOS 5.5 32 bit and kernel 2.6.18-194.26.1.el5PAE #1 SMP . I could not find any other way to figure out what is causing this problem. is it a good idea to use CentOS 64 bit ?

MOH - playing without any issue. I do not think Disk activity is a issue here. 

Box running Intel Core 2 Quad 2.4GHz + 4GB Ram - CentOS FreeSWITCH 

IVR - Start low volume then increase ... sometime high volume then go to low volume
Voice mails - Noice, breaking voices etc ...

Any help is appreciated.

Thanks
