[Asterisk-Users] Removing "-" (Dash) from Dialed Numbers

[Scott Miller]

That solutions kind of works, but only for phone numbers that are in the
format xxx-xxx-xxxx.  The records I am receiving from LDAP vary
significantly because the user can control their entry.  So I can receiving
mostly the following formats.

 

(xxx) xxx-xxxx 

xxx xxx-xxxx

xxx-xxx-xxxx

 

Ideally, I'd like a function that would remove all characters but the
numbers, but I haven't found a way to do that.  If I were more fluent in C,
I might write a module to do it.  Instead, I added some extensions to try to
compensate for the common formats, and it looks like this.

 

[app-clean-ldap]

exten => _XXX-XXX-XXXX,1,SetVar(AreaCode=${EXTEN:0:3})

exten => _XXX-XXX-XXXX,2,SetVar(Prefix=${EXTEN:4:3})

exten => _XXX-XXX-XXXX,3,SetVar(Suffix=${EXTEN:8:4})

exten =>
_XXX-XXX-XXXX,4,Goto(from-internal,91${AreaCode}${Prefix}${Suffix},1)

 

exten => _(XXX) XXX-XXXX,1,SetVar(AreaCode=${EXTEN:1:4})

exten => _(XXX) XXX-XXXX,2,SetVar(Prefix=${EXTEN:5:3})

exten => _(XXX) XXX-XXXX,3,SetVar(Suffix=${EXTEN:9:4}) 

exten => _(XXX)
XXX-XXXX,4,Goto(from-internal,${AreaCode}${Prefix}${Suffix},1)

 

 

exten => _XXX XXX-XXXX,1,SetVar(AreaCode=${EXTEN:0:3}) 

exten => _XXX XXX-XXXX,2,SetVar(Prefix=${EXTEN:4:3}) 

exten => _XXX XXX-XXXX,3,SetVar(Suffix=${EXTEN:8:4}) 

exten => _XXX
XXX-XXXX,4,Goto(from-internal,91${AreaCode}${Prefix}${Suffix},1)

 

 

My only problem now is that I can't pattern match a space character in the
last two sections.  I was able use a period as a wildcard to match the
space, but that returns unexpected results if someone has more than one
character in there.  Does anyone know how to match a space character in the
dial plan?  Help is always appreciated.

 

Thanks,

Scott Miller

Not very elegant, but:

 

exten => 1,1,SetVar(MyNumber=780-555-1212)

exten => 1,2,SetVar(AreaCode=${MyNumber:3:3})

exten => 1,3,SetVar(Prefix=${MyNumber:5:7})

exten => 1,4,SetVar(Suffix=${MyNumber:8:11})

exten => 1,5,Dial(ZAP/g0/1${AreaCode}${Prefix}${Suffix})

I am trying to enable dial-by-email by using LDAPget to query an Active
Directory server.  I've got it retrieving the phone number fine.
Unforunately, the numbers stored in active directory are either in the
format:  (xxx) xxx-xxxx or xxx-xxx-xxxx.   Is there any way to parse
characters out of the dialed phone number so that I only end up with digits
(remove spaces, parenthesis and dashes)?   From there, my outbound routes
can take care of where to send the call.

 

Help is always appreciated! :-)  

 

Thank you,

Scott Miller
