Administrator's Guide for SIP-T2 Series/T19(P) E2/T4 Series/T5 Series/CP860/CP920 IP Phones
The IP phone will wait this many seconds before matching the entered digits to the dial
plan and placing the call.
Valid values are:
Single configuration (configure a specific value for the timer letter "T" for all strings

with "T" of the digit map)
Example:
dialplan.digitmap.interdigit_short_timer = 5
If the value of the parameter "dialplan.digitmap.string" is set to <[2-9]x:86>3.T|0T,
the IP phone will wait 5 seconds before matching the entered digits to this dial
plan and placing the call.
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:
dialplan.digitmap.interdigit_short_timer = 4|5|3|6|2|1
If the value of the parameter "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.
Note: It works only if the value of the parameter "dialplan.digitmap.enable" or
"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
configured by this parameter.
