Note: The string must be compatible with the digit map feature of MGCP described in 2.1.5 of RFC
3435. It works only if “account.X.dialplan.digitmap.enable” is set to 1 (Enabled). The value configured
by the parameter “account.X.dialplan.digitmap.string” takes precedence over that configured by the
parameter “dialplan.digitmap.string”.
Permitted
Values
String within 2048 characters
Default
Blank
Parameter
account.X.dialplan.digitmap.interdigit_long_timer
[1]
<MAC>.cfg
Description
It configures the time (in seconds) to wait before dialing an entered number if it matches part of any
string of the digit map for the account X.
If it is set to 0, the phone will not dial the entered number if only a partial match exists.
The value of this parameter should be greater than that configured by the parameter “accoun-
t.X.dialplan.digitmap.interdigit_short_timer”.
For example:
account.1.dialplan.digitmap.string = 1xxT|xxxxx<T1 >
account.1.dialplan.digitmap.interdigit_long_timer = 10
account.1.dialplan.digitmap.interdigit_short_timer = 5
When you enter 1, it matches part of two-digit maps, the phone tries to wait 10 seconds and then dials
out 1 if no numbers entered;
When you enter 15, it also matches part of two-digit maps, the phone tries to wait 10 seconds and then
dials out 15 if no numbers entered;
When you enter 153, it also matches part of two-digit maps, the phone tries to wait 10 seconds. But
after waiting for 5 seconds, it completely matches the first digit map and then immediately dials out
153.
Note: It works only if “account.X.dialplan.digitmap.enable” is set to 1 (Enabled). The value configured
by the parameter “account.X.dialplan.digitmap.interdigit_long_timer” takes precedence over that con-
figured by the parameter “dialplan.digitmap.interdigit_long_timer”.
Permitted
Values
Integer from 0 to 255
Default
Blank
Parameter
account.X.dialplan.digitmap.interdigit_short_timer
[1]
<MAC>.cfg
Description
It configures the timeout interval (in seconds) for any string of digit map.
The phone will wait this many seconds before matching the entered digits to the dial plan and placing
the call.
Note: It works only if “account.X.dialplan.digitmap.enable” is set to 1 (Enabled). The value configured
by the parameter “account.X.dialplan.digitmap.interdigit_short_timer” takes precedence over that con-
figured by the parameter “dialplan.digitmap.interdigit_short_timer”.
Permitted
Values
Single configuration (configure a specific value for the timer letter “T” for all strings with “T” of the digit
map)
Example:
account.1.dialplan.digitmap.interdigit_short_timer = 5
If “dialplan.digitmap.string” is set to <[2-9]x:86>3.T|0T, the phone will wait 5 seconds before matching
the entered digits to this dial plan and placing the call.
