strings. When the dialed digits match a format string in the DIALPLAN configuration parameter,
the call is initiated.
Valid characters in a format string, and their meanings, are as follows:
• digits 0 through 9, inclusive = Specific dialpad digits
• * = the dialpad character *
• # = the dialpad character # (but only if it is the first character in the dialed string – see below)
• x = any dialpad digit (i.e., 0-9)
• Z or z = present dial tone to the user (for example, for Feature Access Code (FAC) entry)
• [ ] = any one character within the brackets is a valid match for a dial plan string
• - = any one digit between the bounds within the brackets, inclusive, is a match
• + = the character following the + can repeat 0 or more additional times, for a valid match
An individual valid dial plan is any combination of the above characters. If there are multiple valid
dial plans, separate each one from the next using an OR symbol ("|"). If the dial plan text string
begins or ends with an OR symbol, that symbol is ignored. Users cannot modify the dial plan.
Dial plan example:
"[2-4]xxx|[68]xxx|*xx|9Z1xxxxxxxxxx|9z011x+"
where:
• [2-4]xxx: Four-digit dial extensions, with valid extensions starting with 2, 3, or 4;
• [68]xxx: Four-digit dial extensions, with valid extensions starting with 6 or 8;
• *xx: Two-digit Feature Access Codes, preceded by a *;
• 9Z1xxxxxxxxxx: Network Access Code ("9 for an outside line"), followed by dial tone,
followed by any string of 10 digits– typical instance of Automatic Route Selection (ARS) for
standard US long distance number;
• 9z011x+: Network Access Code ("9 for an outside line"), followed by dial tone, followed by at
least one digit – typical instance of Automatic Route Selection (ARS) for US access to
international numbers of unknown, and variable, length.
Additional parameters that affect dialing are as follows:
• COUNTRY - Country of operation for specific dial tone generation.
• PSTN_VM_NUM (PSTN access number for Voice Mail system) - This parameter specifies
the telephone number to be dialed automatically when the deskphone user presses the
Messaging button under a non-AST controller. The deskphone places a PSTN call out from
the local office and back in to the location that houses the voice mail server. Additional codes
necessary to reach a specific user's voice-mail box may also be included. Example 1. SET
PSTN_VM_NUM 96135550123
• ENABLE_REMOVE_PSTN_ACCESS_PREFIX - When the deskphone is operating with a
non-AST controller and the value of the parameter is 0, the PSTN access prefix, defined by
the parameter PHNOL, is retained in the outgoing number. If the value is 1, then the PSTN
access prefix is stripped from the outgoing number.
• PHNLAC - A string representing the deskphone's local area code. When set, this parameter
indicates the endpoint's local area code, which along with the parameter
