Dialed Digit Translator Configuration Examples

Dialed Digit Translator Configuration Examples Introduction:

This document covers some common Dialed Digit Translator configurations. Dialed Digit Translator settings are accessed via the Number Plan tab under System Configuration in AltiAdmin. First Digit Translator allows the administrator to select a single dialed digit that can be assigned to route a call to any destination. Extension Dialed Digit Translator allows predefined dialed digits by any extension to be translated into a different dialing string. The digit manipulation option allows you to move or add digits to a number dialed by the extension.


This feature is capable of intercepting and manipulating a dialed digit string before it is sent out for outbound call processing.

To set up a dialed digit translator entry, check the Enable checkbox and click the Setup key. This opens a dialog box where you can select First Digit Translator or Extension Dialed Digit Translator.

This feature supersedes the first digit assignment of the system number plan. When configured, any extension user can dial a single DTMF digit that will be translated to any internal or external number. After digit manipulation, the translated digits go through the system number plan to find the internal or external target. For example, you can configure “*” to call an internal workgroup to report an urgent situation.


Typical applications:

- One-digit emergency dialing
- One-digit dialing to branch or headquarters over PSTN or VOIP
- One-digit dialing to activate a feature code.
- Setting up certain extensions to dial 9 first. (fax machines)
- Translating numbers dialed from certain employees to other numbers
- Using trunk access by extension (for non Hpbx users)
- Emergency Dialing Support for Remote IP Phones using AltiWare’s Dialed Digits Translator or FXO Gateway*
*See Emergency Number Dialing for Remote IP Phones for details on this configuration.

Please refer to the Setting a system Number Plan section of Chapter 4 in the ACC and ACM Administration manuals for details on the initial setup of Dialed Digit Translator. Below are sample setups of the typical applications listed above.



One-digit emergency dialing:
This is used when the user wants to dial one digit and connect to an emergency number.
For example, the user would like to call 911 by pressing *. This is how it would be setup:
In this case, you would use First Digit Translator.



Select the * and input 911. Now, when a user dials *, it will automatically dial 911.


One-digit dialing to branch or headquarters over PSTN or VoIP:
This is used when the user wants to dial one digit to connect to a secondary server over PSTN or VoIP. For example, the user would like to dial “0” and have it connect to the operator on the other server. In this case, you would again use First Digit translator. Select the “0” and input the [access code for the VoIP trunks] and [location ID of the secondary server] and the [operator’s extension number on the secondary server]
It would look something like this: 81100 Where 8=access code, 1=location ID, and 100=operator’s extension.


Setting up certain extensions to automatically dial 9 (or any other trunk access code):
Many administrators set this up for fax machines so that the user does not have to dial 9 to send a fax. In this case, you would use Extension Dialed Digit Translator. For example, your fax extension is setup as extension 111.

1. In the Extensions Group field, use the Add button to create and select an extension group that the Extension Dialed Digit Translator will apply to, so in this case you would choose 111.

2. For the Manipulation field enter “9” in the Digit Prefix inserted to head field.


Note: Since this configuration forces the extension to dial 9 first on every call, any extensions using this configuration will only be able to dial external numbers.

Translating a number dialed into a different number:
This is typically used to redirect 911 dials from a remote IP phone to a specific 911 center in their area.


1. In the Extensions Group field, use the Add button to create and select an extension group that the Extension Dialed Digit Translator will apply to.

2. Enter digits in the Dialed Number field and Translate To field. Assuming the system is located in the area code 510, when an IP extension user in LA dials “911,” AltiServ will translate the digits into “919495550911.” (9=IP trunk access code, 19495550911=emergency center in LA that covers the remote IP phone user’s area.)


Using trunk access by extension:
This allows a tenant type situation where you want certain extensions to dial certain trunk access codes. In the dialed digit translator for extension setup a dialed number equal to your route access code. Delete the 7 and add back in 799.  99 is the variable 2 digit number that I am using (i.e. 99, 98, 97 etc..) It could be any length.



In the out call routing add a route definition that includes the trunks for that “tenant”.  Delete two digits from head, hence stripping the 99.



In the dialing pattern add an entry with the 99  (or whatever digit represents the “tenant”) and do a match on 13 digits.  2 digits for the code and then 11 for the complete telephone number.  This is a 10 digit dialing example.
