- ! HylaFAX (tm) Dialing String Processing Rules,
- ! for office 3 digit extension systems where you dial 9 for outside lines.
- !
- ! 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
- [^+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
- ^[+]${Country} = ${LDPrefix} ! long distance call
- ^[+] = ${IDPrefix} ! international call
- ^[0-9][0-9][0-9][0-9][0-9]+$ = 9,& ! add 9 for outside calls
- ]
