Summary:                    Random inbound calls do not hear any sound but CLI
says file is playing
Description: 
System works fine most of the time, although on occasion for a few minutes
any new inbound callers are met with no audio. Then the system returns to
normal.
Frustrating for both us and the calling party.

This has been happening from many versions ago, and also through many
versions of misdn from misdn.org.

Any help is most appreciated.

Found problem was due to ztdummy not receiving interrupts from RTC. I ended
up compiling vanilla kernel 2.6.27.10 on Centos 5 box so ztdummy could use
Highres timers instead. Hardware is Dell Poweredge 850.  Seems like every 2
or 3 weeks the server would hiccup with the interrupts, and would take
exactly 5 minutes I believe to start resending them to RTC.
