When you say "Lots of switches" how are they linked? Outside the box idea but if the switch is remembering IP Addresses incorrectly due to change in traffic flow that may cause conflict.
If you want to resolve your conflict issues you can alway statically assign each device. Simply speaking, if you have only 1 DHCP server there is no reason for a conflict except maybe where DHCP does not notice a static device and uses same address [mungyun](but this should auto resolve).
I would imagine the VoIP phones will need a DHCP server and i believe it would be the VoIP gateway doing this. You would also have a server with DHCP for your computer workstations. By any chance is the VoIP System on the same subnet as your data network?
if so i would separate this as there is absolutely no need and is common sense to have them logically separated.

What kind of router? Is the router the one handing out DHCP addresses?

I have had the same problem in my experience certain devices like terminals do not register correctly in DHCP or do not release their lease quick enough - So then another machine try using that IP and causing a conflict I sometimes have issolate IP's from the scope as Foxloxley suggested.
We have also set the lease down to a couples of hours instead of 24
