Mapping is as follows:
Frequency > personality > Zone + Frequency
If you use xml to insert a zone number > than the number of zones it will change it to the next free number. You cannot skip numbers. If you have a zone number that already exists but the name is different it will not change the name or update that zone, but rather insert it at the end. The number and the name must match to update the zone programing.
Zones -> 200 Channels in a zone -> 625 Conventional Personalities -> 255 Frequencies in a personality -> 1250 Scan Lists -> 200 Channels per list -> 30 Unified call contacts -> 2500
