Customizing Your Phone

―91([5-7])1(x)‖ would match ―91511‖, ―91618‖, ―91715‖.

The ―$‖ should be followed by the sequence number of a parenthesis. The ―$‖

plus the sequence number means the whole character or characters placed in

the parenthesis. The number directs to the right parenthesis when there are

more than one. Example:

A replace rule configuration: Prefix: "9([5-7]) (.)", Replace: "5$2". When you

enter "96123" to dial out on your phone, the number will be replaced as "5123"

and then dialed out. ―$2‖ means the characters in the second parenthesis,

that is, ―123‖.

You can configure one or more replace rules (up to 100) to remove the specified string

and replace it with another string. You can configure a pattern with wildcards (refer to

the expression syntax in the table above), so that any string that matches the pattern

will be replaced. This feature is convenient for you to dial out a long number. For

example, a replace rule is configured as ―Prefix: 1‖ and ―Replace: 1234567‖, when you

try to dial out the number ―1234567‖, you just need to enter ―1‖ on the phone and then

press the OK key to dial out.

To add a replace rule via web user interface:

1. Click on Settings->Dial Plan->Replace Rule.

2. Enter the string (e.g., 1) in the Prefix field.

3. Enter the string (e.g., 1234) in the Replace field.

4. Enter the desired line ID in the Account field or leave it blank.

1 2 ... 52 53 54 55 56 57 58 59 60 61 62 ... 125 126
