DIAL PLAN CONFIGURATION FILE

The Dial Plan Configuration File defines rules for gathering digits when dialing a phone number and also defines the
mapping of the gathered digits to a specific target. A sample dial plan is shown below and can be copied and pasted
into a text file for use.

PREFIX_AFTER_STRIP=”” DIAL_STRING=”[email protected]”/>
FIX_AFTER_STRIP=”” DIAL_STRING=”[email protected]”/>

NOTE: All tokens associated with SYSCONFIG and DIGITMAP must appear on separate single lines
in the actual configuration file.

Dial Plan Configuration File Tokens

The following tokens are used for configuring the dial plan configuration file.
The

SYSCONFIG token defines timer configuration and termination digit parameters.

The

FIRST_DIGIT_WAIT token defines the time in milliseconds the phone will wait after going off-hook to enter the first

digit before the a re-order tone is played.
The

INTER_DIGIT_WAIT token defines the time in milliseconds the phone will wait after the first digit is entered before

a re-order tone is played or the number is dialed.
The

TERMINATION_DIGIT token defines the termination digit to be entered if the maximum number of digits have not

yet been entered and the number is to be dialed before the

INTER_DIGIT_WAIT timer is expired.

The

DIGITMAP token defines the mapping of collected digits to an outbound SIP URL.

The

MATCH token defines the digits which MUST be matched when the user begins entering digits for the DIGITMAP

rule to take effect.
The

MIN_DIGITS token defines the minimum number of digits which MUST be entered once that match rule has been

invoked. This number must be greater than or equal to the number of digits in the

MATCH string.

The

MAX_DIGITS token defines the maximum number of digits which MAY be entered after the match rule has been

invoked. The completion of the number can be achieved when the maximum number of digits have been entered or the

TERMINATION_DIGIT is pressed. The MAX_DIGITS parameter MUST be greater than or equal to the MIN_DIGITS

parameter.
The

STRIP_FIRST_DIGITS parameter defines the number of digits that will be stripped from the beginning of the

complete dial string before it is passed to the underlying stack to be dialed. For example, if the user entered 1234 and

STRIP_FIRST_DIGITS was set to 2, the string passed to the underlying stack for dialing would be 34.
The

ADD_PREFIX_AFTER_STRIP token defines a set of prefix characters that are to be applied to the

beginning of the dial string AFTER the

STRIP_FIRST_DIGITS rule has been applied. Adding to the previous example,

if the

ADD_PREFIX_AFTER_STRIP were set to “56” and the user entered 1234, the string passed to the underlying

stack would be 5634.
The

DIAL_STRING token defines the address which will be dialed when a number satisfying the MATCH rule is entered.

The characters “+&” define a wild card, consisting of the digits in the number dialed. In the example shown above, when
any four-digit number that was dialed is entered, it is passed to the stack as “<

four-digit number>@sipgateway.

com>”.

NOTE: Although the wild card parameter is defined in the

MATCH string and in the DIAL_STRING, it as-

sumes that the rules applied for

STRIP_FIRST_DIGITS and ADD_PREFIX_AFTER_STRIP still take

effect before the entered number replaces the wild card in the

DIAL_STRING.
