I might have tried to generalize that even further, though you still have regional issues to worry about. I.e. this won't work for everyone:
@FORMAT_PHONE = (
'%d%d%d', # 911
'%d-%d%d%d', # 1-411
'%d-%d%d%d%d', # 5-1212 ?
'%d%d-%d%d%d%d', # 55-1212 ?
'%d%d%d-%d%d%d%d', # 555-1212
'%d-%d%d%d-%d%d%d%d', # 1-222-2345
'%d%d%d-%d%d%d-%d%d%d', # 212-114-151 ?
'(%d%d%d) %d%d%d-%d%d%d%d', # (800) 555-1212
'+%d (%d%d%d) %d%d%d-%d%d%d%d', # +1 (800) 555-1212
'+%d%d (%d%d%d) %d%d%d-%d%d%d%d', # +01 (800) 555-1212
'+%d%d%d (%d%d%d) %d%d%d-%d%d%d%d', # +011 (800) 555-1212
'+%d%d%d %d (%d%d%d) %d%d%d-%d%d%d%d', # +011 1 (800) 555-1212
'%d%d%d%d%d (%d%d%d) %d%d%d-%d%d%d%d', # 10321 (800) 555-1212
'%d%d%d%d%d %d (%d%d%d) %d%d%d-%d%d%d%d', # 10321 1 (800) 555-1212

# etc...
