[asterisk-users] Cut off + sign in telephonenumber

[Jonas Kellens]

Hello,

I'm trying to cut off the "+" sign if part of a telephone number, but 
not succeeding :

exten => test,n,Set(cid=+99999600)
exten => test,n,Set(regx="([0-9])")
exten => test,n,Set(cid2=$["${cid}" : ${regx}])
exten => test,n,NoOp(cid2=${cid2})

cid2 is empty afterwards...


What I want is to make sure there are only numbers and no other characters.

So +99999600 needs to become 99999600 (without + )
So 99999#600 needs to become 99999600 (without # )


Kind regards,
Jonas.
