Call Features
364
Distribution configuration (configure a string of positive integers separated by “|” for each string of the
digit map in the corresponding position)
If there are more digit maps than timeout values, the last timeout is applied to the extra digit map. If
there are more timeout values than digit maps, the extra timeout values are ignored.
Example:
account.1.dialplan.digitmap.interdigit_short_timer = 4|5|3|6|2|1
If “dialplan.digitmap.string” is set to <[2-9]x:86 > 3.T|2T|1xxT|0x.!|[2-9]11T, 4 is applied to the “<[2-
9]x:86 > 3.T” digit map, 5 is applied to “2T” digit map, 3 is applied to “1xxT” digit map, 6 is applied to
“0x.!” digit map, 2 is applied to the “[2-9]11T” digit map, the last digit 1 is ignored.
Default
3
Parameter
account.X.dialplan.digitmap.no_match_action
[1]
<MAC>.cfg
Description
It configures the behavior when an impossible digit map match occurs.
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.no_match_action” takes precedence over that con-
figured by the parameter “dialplan.digitmap.no_match_action”.
Permitted
Values
0-prevent users from entering a number and immediately dial out the entered numbers
1-the dialing will fail and the phone screen will prompt “Forbidden Number”
2-allow users to accumulate digits and dispatch call manually with the send key or automatically dial
out the entered number after a certain period of time configured by the parameter “dial-
plan.digitmap.interdigit_long_timer”
Default
Blank
Parameter
account.X.dialplan.digitmap.active.on_hook_dialing
[1]
<MAC>.cfg
Description
It enables or disables the entered numbers to match the predefined string of the digit map in real time
on the pre-dialing screen.
To enter the pre-dialing screen, directly enter numbers when the phone is idle.
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.active.on_hook_dialing” takes precedence over that
configured by the parameter “dialplan.digitmap.active.on_hook_dialing”.
Permitted
Values
0-Disabled
1-Enabled
Default
Blank
Parameter
account.X.dialplan.digitmap.apply_to.on_hook_dial
[1]
<MAC>.cfg
Description
It enables or disables the entered number to match the predefined string of the digit map after press-
ing a send key on the pre-dialing screen or pressing the DSS key (for example, speed dial, BLF or pre-
fix DSS key).
To enter the pre-dialing screen, directly enter numbers when the phone is idle.
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.apply_to.on_hook_dial” takes precedence over that
configured by the parameter “dialplan.digitmap.apply_to.on_hook_dial”.
