DTMF Map Configuration - Dial Plan

When a number is dialed, it is compared to the numbers of the DTMF maps:

• If the dialed number matches an entry of the Allowed DTMF Map , the call is accepted.
• If the dialed number matches an entry of the Refused DTMF Map table, then the call is refused and an error tone i.e. reorder tone, network congestion, or fast busy tone is played.
• If the dialed number matches no entry of either the Allowed DTMF Map or the Refused DTMF Map , the call is refused and an error tone i.e. reorder tone, network congestion, or fast busy tone is played.
• If the dialed number matches an entry of both the Allowed DTMF Map and the Refused DTMF Map , the call is refused and an error tone i.e. reorder tone, network congestion, or fast busy tone is played.

  Note

  The Refused DTMF Map table has precedence over the Allowed DTMF Map table.

For example, lets say

• all employees have a 3-digit extension all starting with 1, 2 or 3.
• All managers have an extension finishing with 9

The DTMF map is used to recognise the dialed numbers and the transformation modifies the dialed numbers before sending the call. A transformation is not mandatory, it depends if the dialed number must be changed or not before the call is made.

For example, when the dialed number is the extension of a colleague, no transformation is required. The DTMF map will recognise that the dialed numbers are the allowed extension of a colleague, and the call will be made with the dialed number.

However, in the example where calls made to management extensions are redirected to the management's assistant, a transformation is required. For example, if the DTMF is xx9 and the transformation 123, this means that whenever an extension finishing by 9 is dialed, the call is sent to extension 123.

DigitMap = DigitString / '(' DigitStringList ')'
DigitStringList = DigitString 0*( '|' DigitString ) 
DigitString = 1*(DigitStringElement) 
DigitStringElement = DigitPosition ['.'] 
DigitPosition = DigitMapLetter / DigitMapRange 
DigitMapLetter = DIGIT / '#' / '*' / 'A' / 'B' / 'C' / 'D' / 'T' 
DigitMapRange = 'x' / '[' 1*DigitLetter ']' 
DigitLetter ::= *((DIGIT '-' DIGIT ) / DigitMapLetter) 

Mediatrix user documentation is available on the Documentation Portal at http://documentation.media5corp.com

Several types of documents were created to clearly present the information you are looking for. Our documentation includes:

• Release notes : Generated at each GA release, this document includes the known and solved issues of the software. It also outlines the changes and the new features the release includes.
• Configuration notes : These documents are created to facilitate the configuration of a specific use case. They address a configuration aspect we consider that most users will need to perform. However, in some cases, a configuration note is created after receiving a question from a customer. They provide standard step-by-step procedures detailing the values of the parameters to use. They provide a means of validation and present some conceptual information. The configuration notes are specifically created to guide the user through an aspect of the configuration.
• Technical bulletins : These documents are created to facilitate the configuration of a specific technical action, such as performing a firmware upgrade.
• Hardware installation guide : They provide the detailed procedure on how to safely and adequately install the unit. It provides information on card installation, cable connections, and how to access for the first time the Management interface.
• User guide : The user guide explains how to customise to your needs the configuration of the unit. Although this document is task oriented, it provides conceptual information to help the user understand the purpose and impact of each task. The User Guide will provide information such as where and how TR-069 can be configured in the Management Interface, how to set firewalls, or how to use the CLI to configure parameters that are not available in the Management Interface.
• Reference guide : This exhaustive document has been created for advanced users. It includes a description of all the parameters used by all the services of the Mediatrix units. You will find, for example, scripts to configure a specific parameter, notification messages sent by a service, or an action description used to create Rulesets. This document includes reference information such as a dictionary, and it does not include any step-by-step procedures.
