Managing Linksys 900 Series IP Phones
Implicit Sequences
The 900 Series phone implicitly appends the vertical code sequences entered in the
administration web server Regional parameter settings to the end of the dial plan for both Line
1 and Line 2. Likewise, if <Enable_IP_Dialing> is enabled, IP dialing is also accepted on the
associated line.
Dial Plan Examples
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 xxxxx x. )
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 )
