Q5 How to use dial plan?
A5
：
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
DialPlan::= String | "(" StringList ")"
A dial plan, according to this syntax, is defined either by a (case insensitive) string
or by a list of strings. Regardless of the above syntax a timer is only allowed if it
appears in the last position in a string (12T3 is not valid). Each string is an
alternate numbering scheme. The unit will process the dial plan by comparing the
current dial string against the dial plan, if the result is underqualified (partial
matches at least one entry) then it will do nothing further. If the result matches or
is over-qualified (no further digits could possibly produce a match) then send the
string to the gatekeeper and clear the dial string. The Timer T is activated when it
is all that is required to produce a match. The period of timer T is 4 seconds. For
example a dial plan of (xxxT|xxxxx) will match immediately if 5 digits are entered,
it will also match after a 4 second pause when 3 digits are entered.
