Alternate Number Dialing
Alternate Number Dialing allows you to dial different phone numbers in an attempt to reach a person whose line is
busy.
Alternate Number Dialing is useful when the person or organization you are trying to reach has more than one
number, where they may be reached. The system dials out different phone numbers of the same party, saving your
time and effort of dialing each of these numbers manually.
You simply need to Redial the number or set Auto Redial for the number. Doing so, the system tries alternate
numbers, if programmed. If Auto Redial is requested, the system gives you a ring when the number goes through.
How it works
Global Directory is used to accomplish this feature. An Alternate group number should be assigned to a number in
the Global Directory. An Alternate group number can vary from 00 to 99.
Suppose two numbers programmed at index 10 and 11 are to be used as Alternate numbers. Then both the
numbers should be programmed as one group in the Global Directory. Doing so, when a station user dials an
external number, the system checks for it in the Global Directory. If the number is busy and the user tries Redial,
the system automatically opts for Alternate Number dialing. It tries the next number available in the Alternate group.
If this number is also busy, it tries next number in the group. All the numbers are tried in this way. This continues as
long as the user accesses the Redial feature.
If the user tries Auto Redial, the system tries for all the numbers in the Alternate group one by one. If any of the
number is through, it gives a ring to the caller. If all the numbers are busy in the group then the system sets Auto
Redial for the last number dialed and waits for RBT from the remote end. It informs the caller when the call is
through by placing a ring on your station.
For example, ABC Ltd. has four telephone numbers such as 2640459, 2631235, 2635589 and 2565590 and all are
to be used as Alternate Numbers. So, all these four numbers should be programmed in the Global Directory.
Now you configure them in indexes ranging from 10 to 13. All these numbers should be assigned one Alternate
group, say, 00. Doing so, all these numbers act as the Alternate Number for each other. Whenever a user dials any
of these numbers and tries Redial or Auto Redial, Alternate Number dialing logic comes into play automatically. If a
user dials 2640459 and finds it busy and then tries Redial (or, Auto Redial), the system automatically dials
2631235. This is repeated every time a Redial (or, Auto Redial) is accessed.
If no alternate number is available for a main number in the Global Directory then the system redials the last dialed
number while trying the Redial or the Auto Redial.
• Alternate Numbers are used during Redial and Auto Redial. Hence all the timers related to these
features should be programmed properly.
• If Auto Redial is set for a number having Alternate numbers, the system tries all the Alternate numbers
first and then sets the Auto Redial for the last number dialed.
• One number can have one or more than one Alternate numbers. Maximum 90 alternate numbers can
be assigned to a number.
