! HylaFAX (tm) Dialing String Processing Rules.
!
! This file describes how to process user-specified dialing strings
! to create two items:
!
! CanonicalNumber: a unique string that is derived from all dialing
! strings to the same destination phone number. This string is used
! by the fax server for ``naming'' the destination.
!
! DialString: the string passed to the modem for use in dialing the
! telephone. This string should be void of any characters that might
! confuse the modem.
!
Area=${AreaCode} ! local area code
Country=${CountryCode} ! local country code
IDPrefix=${InternationalPrefix} ! prefix for placing an international call
LDPrefix=${LongDistancePrefix} ! prefix for placing a long distance call
!
WS=" " ! our notion of white space
!
! Convert a phone number to a canonical format:
!
! +<country><areacode><rest>
!
! by (possibly) stripping off leading dialing prefixes for
! long distance and/or international dialing.
!
CanonicalNumber := [
%.* = ! strip calling card stuff
[abcABC] = 2 ! these convert alpha to numbers
[defDEF] = 3
[ghiGHI] = 4
[jklJKL] = 5
[mnoMNO] = 6
[prsPRS] = 7
[tuvTUV] = 8
[wxyWXY] = 9
[^+0-9]+ = ! strip white space etc.
^${IDPrefix} = + ! replace int. dialing code
^${LDPrefix} = +${Country} ! replace l.d. dialing code
^[^+] = +${Country}${Area}& ! otherwise, insert canon form
]
!
! Process a dialing string according to local requirements.
! These rules do only one transformation: they convert in-country
! international calls to long-distance calls.
!
DialString := [
[-${WS}.]+ = ! strip syntactic sugar
[abcABC] = 2 ! these convert alpha to numbers
[defDEF] = 3
[ghiGHI] = 4
[jklJKL] = 5
[mnoMNO] = 6
[prsPRS] = 7
[tuvTUV] = 8
[wxyWXY] = 9
^[+]${Country} = ${LDPrefix} ! long distance call
^[+] = ${IDPrefix} ! international call
