.
The dot “.” can be used as a placeholder or multiple placeholders,
including zero, of occurrences of the preceding construct.
Examples:
“123.T” would match “12
3
”, “12
33
”, “12
333
”, “12
3333
”, etc.
“x.T” would match an arbitrary number.
“[x*#+].T” would match an arbitrary character.
Note
: If the string ends with a dot (e.g., 123.), a match will occur
immediately after inputting the characters before the dot (e., 123)
since the dot allows for zero occurrences of the preceding construct.
So we recommend you to add a letter “T” after the dot (e.g., 123.T)
for inputting more characters.
R
The letter “R” indicates that certain matched strings are replaced.
Using a RRR syntax, you can replace the digits between the first two
R s with the digits between the last two R s. Example:
“R12R234R” would replace 12 with 234.
<:>
The letter “:” in the angle bracket indicates that certain matched
strings are replaced. Using the <:> syntax, you can replace the digits
before the colon with the digits after the colon.
Example:
“<12:234>” would replace 12 with 234. It is the same with R12R234R.
!
The exclamation mark “!” can be used to prevent users from dialing
out specific numbers. It can only be put last in each string of the digit
map.
Example:
“235x!” would match “2351”, “2352”, “2353”, etc. The number starting
with 235 will be blocked to dial out.
,
The comma “,” can be used as a separator to generate secondary dial
tone.
Example:
“<9,:55>xx”, after entering digit “9”, secondary dial tone plays and
you can complete the remaining two-digit number.
Note: The secondary dial tone can be customized. For more
information, refer to Tones on page 784.
