Syntax of the Destination Patterns in the Service Plans
A Service plan can contain Minute Plans with certain amount of included minutes. To apply a Minute Plan to a specific set of destinations only, a Destination Pattern can be specified.
The Destination Pattern field can contain several prefixes separated 
with whitespace. 
The prefixes can be of two types - positive and 
negative. A negative prefix starts with the symbol ^. 
The prefix can also contain a wildcard symbol . (dot) that matches any digit.
Example 1
Destination Pattern: 
111 ^1114 | 
This pattern matches all destinations starting with 111 but not starting with 1114. So the destinations 11155555 and 1110000000 match, and destinations 111456, 11147777 and 55555 don't match.
Example 2
Destination Pattern: 
111 ^1114 11141 | 
This pattern matches the destinations 111222 and 11141222, and doesn't match the 1114222.
Example 3
Destination Pattern: 
111.2 | 
This pattern matches the destinations 111222 and 11142555, and doesn't match the 11133333.
