/*
This is the specification for the implementation of the phone number parser.
This has been provided by Pekka Jokela (Nokia).
1. If the first character of the number is '+', the '+' character is
left out, and the real phone number is considered to begin right after
that.
* If there is a '(' as the first character and the plus sign follows then
i.e. first two characters = '(+' then they must both be removed and the
real phone number is considered to begin after them
2. If the number begins with a '*' or '#' symbol, all characters to
the last '*' or '#' symbol are ignored, and the real phone number is
considered to begin right after that.
* If there is '+' character right after the last '#' or '*', the '+'
character is left out, and the real phone number is considered to
begin after that.
* If there is '+' character within first five characters, all
characters to the '+' symbol are ignored, and the real phone number is
considered to begin right after that.
3. If the number contains special characters 'p',' w' and '+' , all
characters after the first special character are ignored.
If the number contains '*' and '#' symbols, i.e. there is a
supplementary service code or a feature code within the number:
* If the code is finished by '*' or by '# the real phone number can
be separated easily (refer to the table below, example 1). Even
possible '+' symbol after the code can be left out (example 2).
* If the code is finished by a digit, the real phone number can not be
separated from the code. In most cases, this is not a problem, because
only seven last digits are significant for comparison (example 3). If
there is '+' symbol between the code and the real phone number, the
'+' has to be within first five characters or otherwise it is
considered to start a DTMF function. (example 4)
These all match 1234567:
*#42# 0401234567 p123
*#42# +358401234567 p123
*61 0401234567
*61 +358401234567
+358401234567 +3
+358401234567 p123
(+358) 1234567
And these something else:
*#42# 0401234567#p123 -> empty
*12345+0401234567 -> 12345
*+123+456+++++++++++ ->123
The relevant ETSI specifications are:
ETSI 02.07 - MS Features. Section B.3.4.
ETSI 03.14 - Defines what DTMF digits are.
ETSI 11.11 - Section 10.5.1. Defines the Separator digit.
