{ ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. |
[3469]11 }
Explanation of example rule (reading from left to right):
• ^1900x. - prevents dialing any number started with 1900
• <=1617>[2-9]xxxxxx - allows dialing to local area code (617) numbers
by dialing 7 numbers and 1617 area code will be added automatically
• 1[2-9]xx[2-9]xxxxxx - allows dialing to any US/Canada Number with 11
digits length
• 011[2-9]x. - allows international calls starting with 011
• [3469]11 - allow dialing special and emergency numbers 311, 411, 611
and 911
Note: In some cases, user wishes to dial strings such as *123 to activate
voice mail or other application provided by service provider. In this case *
should be predefined inside dial plan feature. As an example { *x+ } will allow
to dial * followed by any length of numbers.
