“+” repeat previous digit any number of times (0 to 255)

“x” match any numerical digit (0-9)

“~” matchanydigit(0-9,A-D,*,#)excludinganyspeciedterminators

“!” disallows pattern

“$” indicatessecondarydialingtofollow-usedonlybyxeddialstrings

“<:>” replace group to replace left digit(s) with right digit(s)

“[]” selection group of candidate digits

“[^]” exclusion group of digits

“[0-9]” selection range of candidate numerical digits

“[a-d]” selection range of candidate letter digits

“s” seize on string as only candidate if match to this point

“e” specify ending termination digit which follows (usually * or #)

“f” pause timeout causes failure instead of dial

“p” set digit pause to number of seconds which follow (1-9) for current pattern

“t” set digit timeout to default for current pattern

“-” human readable spacing which is ignored

Interdigittimeout,orpause:Bydefault,thedeviceallowsve(5)secondsbetweendialeddigits.To

changethisdefault,youmustinsertthe“p”parameterbeforethepointinthematchstringthatyou

want this parameter to change. For example, if you would like a nine (9) second delay after each digit is

pressed,thenyouwouldneedtoenter“p9”atthebeginningofthepatternmatchingstring.Similarly,if

you would like a shorter timeout of three (3) seconds towards the end of a dial string, you would need to

Examples of dial strings:

Each parameter in a pattern match string represents a single digit. The only exceptions are parameters

that include a repeat operator. We will illustrate these features by examining the entries in the default

VoIP dial string:

0Se#r5xp2r*x[3469]11

Recognize the sequences 311,411, 611 and 911, and send them to the service provider when com-

plete.

[3469]means“either3OR4OR6OR9”.Theentirestringmeans“either3OR4OR6OR9”followed

by “11”.

This string allows the ATA to recognize and forward feature codes to the service provider. However, note

that by default, feature codes are handled locally, in the ATA. The ATA refers to this string only if the re-

mote or default feature code parameters are enabled, or if Pass Through mode is enabled. In those cases,

this string must be included in the pattern matching string, so that the ATA will forward feature codes to

the service provider.
