2.
Allow dialing numbers whose length is 4 and begin with * or #.
3.

The following dial plan accepts only US-style 1 + area-code + local-number, with no
restrictions on the area code and number.
(1 xxx xxxxxxx)
The following also allows 7-digit US-style dialing, and automatically inserts a 1 + 212
(local area code) in the transmitted number.
(1 xxx xxxxxxx | <:1212> xxxxxxx)
For an office environment, the following plan requires a user to dial 8 as a prefix for local
calls and 9 as a prefix for long distance. In either case, an “outside line” tone is played
after the initial 8 or 9, and neither prefix is transmitted when initiating the call.
(<9, :> 1 xxx xxxxxxx | <8,:1212> xxxxxxx )
The following allows only placing international calls (011 call), with an arbitrary number
of digits past a required 5 digit minimum, and also allows calling an international call
operator (00). In addition, it lengthens the default short interdigit timeout to 4
seconds.
S: 4, (00 | 011 xxxxxx.)
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)

unless a 4 digit extension is dialed by the user.
