Do a search through the archives. Some IDE subsystems are known to hold
interupts too long and they interfere with the need for Zap devices to
be services 1000 times per second. If you don't service the zap devices
on time and without misses you will have degraded voice quality and
possibly, if on PRI, you could screw up a call setup or tear down.
