Digit Maps Timeouts
You can define timeouts that apply to the whole unit when dialing a digit map.

To configure digit map timeouts:
1. In the digitMapMIB ( digitMapTimeouts group), define the total time the user has to dial the DTMF
sequence in the digitMapTimeoutCompletion variable.
The timer starts when the dial tone is played. When the timer expires, the receiver off-hook tone is
played.
This value is expressed in milliseconds (ms). Values range from 1000 ms to 180000 ms. The default
value is
60000 ms.
2. Define the time between the start of the dial tone and the receiver off-hook tone, if no DTMF is
detected, in the
digitMapTimeoutFirstDigit variable.
This value is expressed in milliseconds (ms). Values range from 1000 ms to 180000 ms. The default
value is
20000 ms.
3. Define the value of the “T” digit in the digitMapTimeoutInterDigit variable.
The “T” digit is used to express a time lapse between the detection of two DTMFs.
This value is expressed in milliseconds (ms). Values range from 500 ms to 10000 ms. The default
value is
4000 ms.
Digit Map Examples
Digit Map Example 1 – Standard Calls
Let’s say you are located in Seattle, Washington and you want to define digit map rules for your users. You
must consider at least four possibilities:

You are making a long distance call outside the country.

You are making a long distance call outside your area code.

You are making a local call outside your area code (in the 425 area code).

You are making a local call in the same area code.
Digit Map Rule #1
This digit map rule checks for calls outside the country.

A valid telephone number must contain a country code, an area
code, and a number – the “011” part is not required.
