Using Dial Plans
The following allows only US-style 1 + area-code + local-number, but disallows area codes and local
numbers starting with 0 or 1. It also allows 411, 911, and operator calls (0).
( 0 | [49]11 | 1 [2-9]xx [2-9]xxxxxx )
The following allows US-style long distance, but blocks 9xx area codes:
( 1 [2-8]xx [2-9]xxxxxx )
The following allows arbitrary long distance dialing, but explicitly blocks the 947 area code.
( 1 947 xxxxxxx ! | 1 xxx xxxxxxx )
The following implements a hot line phone, which automatically calls 1 212 5551234.
( S0 <:12125551234> )
The following provides a warm line to a local office operator (1000) after five seconds, unless a
four-digit extension is dialed by the user.
( P5 <:1000> | xxxx )
