Only 8 sites? A walk in the park. My 68 nodes play nicely together, but only because the numbering plan was well thought out.
I used 4 through 7 for extension numbers, 2 for voice mail applications, 3 for feature codes, and 9 for all trunks and trunk groups (which also should be unique). Use feature keys, end users should never be expected to remember feature codes.
Forget about reserving 1,000 number blocks for extensions. You'll run out of numbers before using a fraction of the system capacity.
Reserve smaller blocks: 4100 to 4199, 4200 to 4299, etc. Actual size will be determined by the anticipated number of phones, leaving plenty of room for expansion.
Number your hunt groups within the reserved block, so you can instantly identify which site it belongs to. Reserve 2xxxx blocks for voice mail applications, for the same reason. You'll just make yourself crazy if you mix everything together randomly.
Number your IP Connections to match the node number: P6001 and P6101 for Node 1, P6002 and P6102 for Node 2, etc. You'll know instantly what you're looking at.
Create a detailed spreadsheet to document your numbering plan before even thinking about starting any programming. Let me know if you have any specific questions.
