Address book formats numbers for you in custom ways this is good. but sometimes these numbers might be saved with spaces in them, i noticed this when another application was using the address book and displayed a few numbers with unexpected spaces.
this little script will do a check for you and if you want to it can fix them as well:
the check will not modify your address book at all and will give you a count and names that would be affected if you were to do a fix.
AS A PRECAUTION JUST TO BE SAFE: If you are going to do a FIX do backup of your address book database first
set nameList to " names have a space in one of their phone numbers:\n"
display dialog "" buttons {"Check", "Fix"} default button 1
if the button returned of the result is "Fix" then
set Fix to 1
else
set Fix to 0
end if
tell application "Address Book"
set counter to 0
repeat with thisPerson in every person
set theirName to ""
repeat with theirPhone in every phone of thisPerson
if the value of theirPhone contains " " then
set counter to counter + 1
set theirName to first name of thisPerson & "\n"
if Fix is equal to 1 then
try
set theNumber to value of theirPhone
set value of theirPhone to do shell script "echo " & theNumber & "| tr -d ' ' "
end try
end if
end if
end repeat
set nameList to nameList & theirName
end repeat
end tell
display dialog (counter as string) & nameList
