Dial Plan Support for Secondary Dial Tone

The IP phones now support a feature that allows the user to dial a predefined dial string, obtain a dial tone, and continue dialing. A User or Administrator can configure this using the existing Dial Plan feature on the phone.

You can enter a new character string in the dial plan that allows you to configure the secondary dial tone. The character string is of the form ".;." , where the period indicates an arbitrary number of digits and the semicolon indicates that the phone is to present a dial tone after the previous dialed digit. For example, in the string:

"9;xxxxx"

the user dials “9” to get the outside line, listens for the dial tone, and continues to dial the applicable number. The “;” tells the phone to present a second dial tone after the previously dialed digit. “The “xxxxx” in the example tells the phone that a phone number is dialed after the secondary dial tone is audible.

You can enter the Secondary Dial Tone string in the Dial Plan using the configuration files or the Aastra Web UI.

You use the following parameter in the configuration files to configure a secondary dial tone:

•sip dial plan

Example: sip dial plan: “9;xxxxxxx”
