Appendix, Dial Plan....................................................................
The H.323 and SIP code will allow provisioning (via web browser) of the dial plan. A
dial plan gives the unit a map to determine when a complete number has been
entered and should be passed to the gatekeeper for resolution into an IP address.
Dial plans are expressed using the same syntax as used by MGCP NCS specification.
The formal syntax of the dial plan is described by the following notation:
Digit= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
Timer= "T" | "t"
Letter = Digit | Timer | "#" | "*" | "A" | "a" | "B" | "b" | "C" | "c"| "D" | "d"
Range= "X" | "x" -- matches any digit
| "[" Letters "]" -- matches any of the specified letters
Letters= Subrange | Subrange Letters
Subrange= Letter -- matches the specified letter
| Digit "-" Digit -- matches any digit between first and last
Position= Letter | Range
StringElement= Position -- matches any occurrence of the position
| Position "." -- matches an arbitrary number of occurrences
including 0
String = StringElement | StringElement String
StringList= String | String "|" StringList
Dial Plan= String | "(" StringList ")"
A dial plan, according to this syntax, is defined either by a (case insensitive) string or
