[Asterisk-Users] still some moh troubles

[Anthony Rodgers]

Hi Bart,

If it's anything like the problem we had, you are probably getting what 
sounds like screeching noises during MOH playback? We had this problem 
and made it go away by turning off hyperthreading in the server BIOS 
and starting Linux with noht - this was on a dual Xeon machine.

Hope this helps.

Regards,
