First of all, I suggest expanding the extension range:
extensions 1 to max;
This gives you 2^29 numbers to work with (the remaining three bits are
reserved by the wire format to identify types).
Now you can easily assign a large range of extension numbers to each office,
or even to each developer, and they can use them as they see fit.
Or if you just chose numbers randomly, you'd have to have around 10k
extensions before you'd need to start worrying about collisions.
