Example of a simple dial plan used in a Home/Office in the US:
{ ^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
\+x+ - allow dialing any digit with leading + sign; example: +16175669300
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. An example dial plan will be: { *x+ } which
allows the user to dial * followed by any length of numbers.
Use # as Dial Key
Treats “#” as the Send(or Dial”) key. If set to No”, this “#” key can be included
as part of the dialed number. Default is Yes.
Match Incoming
Caller ID
Specifies matching rules with number, pattern or Alert Info text. When the incoming
caller ID or Alert Info matches the rule, the phone will ring with selected distinctive
ringtone. Matching rules:
Specific caller ID number. For example, 8321123;
A defined pattern with certain length using x and + to specify, where x could be
any digit from 0 to 9. Samples:
xx+ : at least 2-digit number;
xx : only 2-digit number;
[345]xx: 3-digit number with the leading digit of 3, 4 or 5;
[6-9]xx: 3-digit number with the leading digit from 6 to 9.
Alert Info text
Users could configure the matching rule as certain text (e.g., priority) and select the
custom ring tone mapped to it. The custom ring tone will be used if the phone
receives SIP INVITE with Alert-Info header in the following format:
Alert-Info: <http://127.0.0.1>; info=priority
Selects the distinctive ring tone for the matching rule. When the incoming caller ID
or Alert Info matches the rule, the phone will ring with the selected ring.
