Managing Extension Lists63
Within an extension list, you can assign a priority to each extension. 
When the system accesses an extension list, it tries to use the highest 
priority extension first. The highest priority is 1 and the lowest is 99.
For example, If the extension list contains extensions that are assigned to 
T1 channels, you can assign unique priorities to each of the extensions. 
If you instruct the system to place an outgoing call using the T1 line, 
it attempts to use the highest priority...

Cycle Extensions checkbox. Each time the system accesses the extension 
list, it uses the next extension in the list. Calls effectively progress through 
the list to balance the load of calls. If Cycle Extensions is not checked, the 
extension selection always starts from the top of the list.
If an extension in the list has a higher priority, the highest priority 
extension is used regardless of the Cycle...
