Operational Features
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;5551313"
