Second Dial Tone
This feature provides dial tone for outgoing calls on any PRI line, based on the digits dialed. Digits
dialed must match an entry in the second dial tone table to enable a second dial tone. Dial tone
occurs on the line until another digit is dialed, a timeout occurs, or the user hangs up.
Up to 10 separate entries can be stored in the second dial tone table. The maximum digit length for
each entry is four. Each entry must be unique and cannot conflict with:
• Internal DNs
• Hunt Group DNs
• DISA DNs
• Auto DNs
• Target Line DNs
The following paths indicate where to configure the Second Dial Tone in Element Manager and
through Telset Administration:
• Element Manager: Telephony > Dialing Plan > Routing > Second Dial Tone
• Telset interface: **CONFIG > Services > Routing Service > 2nd Dial Tone
First Route <configured route #> This is the route that the system will use, during the indicated
schedule, when the destination code is added to the dial string.
Absorbed Length All, None, 1-X This indicates how much of the destination code gets removed
before the system sends the dial string to the network.
Second Route <configured route #> This is the route the system will use if the first route is unavailable.
Absorbed Length All, None, 1-X This indicates how much of the destination code gets removed
before the system sends the dial string to the network.
Third Route <configured route #> This is the route the system will use if the first and second route
are unavailable.
Absorbed Length All, None, 1-X This indicates how much of the destination code gets removed
before the system sends the dial string to the network.
Tips: Entries can match destination or access codes for outgoing lines.
