When you dial a number on your phone, you enter a series of digits. When you set up a speed-dial number,
the speed-dial number must contain all the digits you need to make the call. For example, if you need to
dial 9 to get an outside line, you enter the number 9 and then the number you want to dial.
You can also add other dialed digits to the number. Examples of additional digits include a meeting access
code, an extension, a voicemail password, an authorization code, and a billing code.
The dial string can contain the following characters:
0 to 9
Pound (#)
Asterisk (*)
Comma (,) This is the pause character, and gives a 2- second delay in the dialing. You can have
several commas in a row. For example, two commas (,,) represent a pause of 4 seconds.
The rules for dial strings are:
Use the comma to separate the parts of the dial string.
An authorization code must always precede a billing code in the speed-dial string.
A single comma is required between the authorization code and the billing code in the string.
A speed-dial label is required for speed dials with authorization codes and additional digits.
Before you configure the speed dial, try to dial the digits manually at least once to ensure that the digit sequence is correct.
Your phone does not save the authorization code, billing code, or extra digits from the speed dial in the call history. If
you press Redial after you connect to a speed-dial destination, the phone prompts you to enter any required authorization
code, billing code, or additional digits manually.
To set up a speed-dial number to call a person at a specific extension, and if you need an authorization code and billing code,
consider the following requirements:
You need to dial 9 for an outside line.
You want to call 5556543.
You need to input the authorization code 1234.
You need to input the billing code 9876.
You must wait for 4 seconds.
After the call connects, you must dial the extension 56789#.
