07551:-0755" in PSTN, which indicates that dial 0755 Gateway, deleted (-0755)
dial "9" to get outside line, then dial the remaining numbers after 0.5 seconds. If

5.1. Basic rules of grammar

1. Rules can be separated by "|", such as "00:-00|0:-0+86|:+86755"
2. Rules are matched by Sit-to-right, when encounter appropriate one, end the
match immediately, or continue next one.
3. Syntax rules is "AA: -aa+bb"，such as "0:-0+86"，"AA" is the matching numbers,
in the back of the colon is the corresponding concrete operation. If succeed, minus
"aa" and "bb", if not, continue next one. If the back of colon without operation,
such as"00:", do not make any operation and exit. If in front of the colon without
string, such as ":+86755", do operation.
4. Dialing rules have no range, its syntax rule is "[A-B]A:-aa+bb" or "A[A-B]:-aa+bb".
For example: The range of 2 to 8 is that: "[2-8]:-aa+bb"or13 to 15 is
"1[3-5]:-aa+bb".
Such as:
1. Rules: "0:|:0755".
a. Input"02083185711"，output"02083185711"；
b. Input"83185700"，output"075583185700".
2. Rules: "00:-00|0"-0+86|:+86755".
a. Input"008522343318"，output"8522343318"；
b. Input"02083185711"，output"862083185711"；
c. Input"83185700"，output"8675583185700".
