asterisk users - Mar 2011 - [1.4] Reading phone number the French way?

Hello,

I need to write a script which prompts the callee to type a number,
and then read it back to them as confirmation:

======= extensions.conf
[robocall]
;Expect 10-digit number excluding final #, 2 tries, 20s time-out
exten => s,n(nbr2call),Read(NBR2CALL,please-type-number,10,,2,20)

exten => s,n,GotoIf($[${LEN(${NBR2CALL})} != 10]?end)
;exten => s,n,SayDigits(${NBR2CALL})
exten => s,n,SayNumber(${NBR2CALL})

exten => s,n(end),Hangup()
======= 

Besides the fact that my Asterisk setup only has US sound files in
/var/lib/asterisk/sounds/digits/, I was wondering how to get Asterisk
to read back the number the French way, ie. digits are read by pairs
to the exception of the leading tuple that always starts with 0.

For instance, a landline number in Paris like 01 42 92 81 00 is read
"zero-one, forty-two, ninety-two, eighty-one, zero-zero", where I
assume Americans would read all the digits individually ("zero, one,
four, two, etc.")

Has someone already looked into this and knows how to solve it?

Thank you.

When you compile asterisk you can select multiple language files by using
"make menuselect" additionally you find lot of free sources on
internet for
language files. Simply create a folder with language short-code in sounds
and then set channel's language variable to that short-code.

Maybe something like:

exten => s,n,SayDigits(${NBR2CALL:0:1})
exten => s,n,SayNumber(${NBR2CALL:2:2})
exten => s,n,SayNumber(${NBR2CALL:4:2})
exten => s,n,SayNumber(${NBR2CALL:6:2})
exten => s,n,SayNumber(${NBR2CALL:8:2})

Or make changes in say.conf.

Apparently, the right way to read a phone number back to the user is
not to use SayNumber() (which might be OK for US-style reading) but
rather Playback(<prefix>:<number>,say), which will then rely on
say.conf

For instance:
======= extensions.conf
exten => 2222,1,Set(NBR2CALL=0142928100) ;exten =>
2222,n,SayNumber(${NBR2CALL}) exten =>
2222,n,Playback(phone:${NBR2CALL},say)
======= 

Using this almost works:
======= say.conf
_pho[n]e:0[1-9]XXXXXXXX => num:${SAY:0:1}, num:${SAY:1:1},
num:${SAY:2:2}, num:${SAY:4:2}, num:${SAY:6:2}, num:${SAY:8:2}
======= 

The remaining problem is when a couple starts with a zero, eg. 01
(should be read "zero one"): In this case, Asterisk ignores the
leading zero and simply pronounces the second digit ("one")

Does someone know of a trick so that the pattern handles couples that
have a leading zero?

Thank you.

Look at the GotoIf statement for example

exten => _9X.,1,GotoIf($["${EXTEN:1:2}" = "00"]?ft)
exten => _9X.,n,GotoIf($["${EXTEN:1:2}" = "08"]?ft)
exten => _9X.,n,GotoIf($["${EXTEN:1:2}" = "06"]?ft)
exten => _9X.,n,GotoIf($["${EXTEN:1:1}" = "3"]?ft)
exten => _9X.,n,GotoIf($["${EXTEN:1:1}" = "1"]?ft)
exten => _9X.,n,GotoIf($["${TMP:0:2}" != "OK"]?ft)
exten => _9X.,n, ...
exten => _9X.,n(ft),  ...

Thanks Dave for the tip, but I found that I needed to change a pattern
that was already in say.conf:

======[fr](date-base,digit-base)     ;BAD _[n]um:0. => num:${SAY:1}
_[n]um:0X => num:${SAY:0:1}, num:${SAY:1:1}
	...

    ;regular phone numbers : landlines and cellphones
;_pho[n]e:0[1-9]XXXXXXXX => num:${SAY:0:1}, num:${SAY:1:1},
num:${SAY:2:2}, num:${SAY:4:2}, num:${SAY:6:2}, num:${SAY:8:2}
======
If I got it right, the way say.conf works, is that it reads the whole
say.conf to make a list of the different patterns. Then, when reading
a prefix+number, it reads the patterns on the right side and tries to
find if it furthers matches another pattern.

In the example above, "_[n]um:0X" will match
"num:${SAY:6:2}", which
will read the two digits as expected, ie. without ignoring a leading
zero.

Thank you.
