{ ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx |
011[2-9]x. | [3469]11 }

• ^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 where the user wishes to dial strings
such as *123 to activate voice mail or other applications
provided by their service provider, the * should be
predefined inside the dial plan feature. An example dial
plan will be: { *x+ } which allows the user to dial * followed
