Ok, so it sounds like this is a quality of service (poor quality issue).  Let me get a few questions answered here:

  1. How long has this been happening?
  2. Is it happening on one phone or all phones?
  3. Do you have more than one location?  Is it happening at all locations?
  4. How often does this occur?
  5. What type of firewall do you have?

  7. Have there been any changes to the network which may have caused this to start?
