Dial Plan Parameters

Last Updated : Apr 27, 2018 |

The Dial Plan Parameters screen works with the Dial Plan Analysis Table to define the system dial plan.

It also controls the appearance of digit extensions on station displays. These multi-digit extensions can be hard to read as a block. Using Communication Manager you can select the display format for 6- to 16-digit extensions.

AAR/ARS Internal Call Prefix

The digits entered here get concatenated with the calling or called extension. Accepts up to eight digits that excludes * or #. Available only when ARS/AAR Dialing Without FAC is enabled for the system. Requires administration of AAR/ARS Internal Call Total Length.

AAR/ARS Internal Call Total Length

Available only if ARS/AAR Dialing Without FAC is enabled for the system.

Valid Entry

Usage

6 to 10

blank

The total length of the internal call digit string, including the Internal Call Prefix and the calling or called extension. Requires administration of an AAR/ARS Internal Call Prefix.

Note:

The longest extension length on the Dial Plan Analysis table, plus the length of the ARS/AAR Internal Call Prefix, must be equal to or greater than the ARS/AAR Internal Call Total Length value.

Call Type Analysis Behavior When Extension Not Assigned

Use this field to specify how Communication Manager must route a call when:

  • The dialed string matches an ext or udp entry in the Call Type Analysis table.

  • The resulting extension is valid, but unassigned.

Note:

You can define valid extensions by assigning the network extensions to a block of numbers in the Uniform Dial Plan table.

Valid entry

Usage

intercept-treatment

Communication Manager stops processing the digits and routes the call to the appropriate intercept treatment:

  • For a local call, the intercept treatment is defined in the Invalid Number Dialed Intercept Treatment field.

  • For a trunk call, the intercept treatment is defined in the DID/Tie/ISDN/SIP Intercept Treatment field.

try-next-choice

Communication Manager processes the next administered choice. If the next choice is not administered, Communication Manager routes the call using the original digits. The default option is try-next-choice.

ETA Node Number

Valid Entry

Usage

1 to 999

blank

The number of the destination server for Extended Trunk Access (ETA) calls. ETA calls are unrecognized numbers you can send to another switch for analysis and routing. Such numbers can be Facility Access Codes, Trunk Access Codes, or extensions outside the UDP table.

ETA Routing Pattern

Valid Entry

Usage

1 to 999

The number of the routing pattern to reach the destination server.

Local Node Number

Valid Entry

Usage

1 to 63

Identifies a specific node in a server network. Must match the DCS switch node number and the CDR node number if they are specified.

blank

Leave blank if automatic restoration, DCS, and CDR are unused.

Retry ARS/AAR Analysis if All-Location Entry Inaccessible

Available with Communication Manager Release 4.0.x or later.

Valid Entry

Usage

y

The system finds and uses the best possible entry in the per-location ARS table, if the all-location table points to a trunk group that cannot be accessed because the network has fragmented.

n

The system stops retry of ARS analysis when a trunk group cannot be accessed as a result of the network being fragmented.

UDP-ARS Calls Considered Offnet

Valid entry

Usage

y

If you set the Net field to ARS and the UDP-ARS Calls Considered Offnet field to y, the call is offnet.

If UDP-ARS calls are off-net then:

  • Users with the COS setting Restrict Call Fwd-Off Net enabled cannot forward calls to a UDP-ARS number.

  • Stations that are outward-restricted (through the COR) cannot place calls to a UDP-ARS number.

  • Toll analysis is applied when a call is placed by a toll-restricted user to a UDP-ARS number.

  • COR-COR checks are inapplicable when a user dials a call to a UDP-ARS number.

n

If you set the Net field to ARS and the UDP-ARS Calls Considered Offnet field to n, the call is onnet.

For more information about the Net field, see Uniform Dial Plan Table section of the Avaya Aura® Communication Manager Screen Reference.

UDP Extension Search Order

Specifies the first table to search to match a dialed extension. If the dialed extension is not found in the specified place, the system searches for the dialed extension in the alternate place. Available if Uniform Dialing Plan is enabled for the system.

Valid Entry

Usage

local-extensions-first

Searches the local server first to match a dialed extension, and if not found, then uses the UDP tables to route the call.

udp-table-first

Searches the UDP tables for an off-switch conversion, and if not found, then searches the local server for the dialed extension.

EXTENSION DISPLAY FORMATS

Extension display format

Specifies how the system punctuates extensions for display. The punctuation field is divided into two columns, one for Inter-Location/SAT displays, and one for Intra-Location displays.

In Communication Manager 6.0, the Inter-Location/SAT column is divided into two columns. You can insert a dial prefix in the Inter-Location column, if appropriate, before an enbloc extension. With this, called stations can store a dialable number in their call logs.

Note:

The maximum length of a displayed extension (including punctuation) varies based on the extension length — for example, for a 10–digit extension, the maximum punctuated length is 13 characters. You must trade off a punctuation mark so that you can insert a prefix digit. You cannot insert a prefix digit or a punctuation mark into the inter-location format for an extension of length 13,14,15, or 16.

Blank spaces are sometimes used in telephone extensions, especially outside of the U.S. Dots (.) are used on SAT screens in place of blanks. The following table gives the maximum number of punctuation marks permitted for each extension length.

The number of punctuation marks that the system supports is determined by the number of xs in the format.

  • If the format contains fewer than six x's, no punctuation marks can be entered.

  • If the format contains six or more x's, the maximum number of punctuation marks is determined by the following table.

Usage

xx.xx.xx

Can contain all x characters (no punctuation) or a combination of x characters and 0 to 2 hyphens (-), spaces, or periods (.) to depict how extensions display. A format must be specified or the default takes effect. This field cannot be left blank. The default values for the 8-, 9-, 10-, 11-, 12-, 13- and 16-digit fields are shown in the following example.

Location-Based Call Type Analysis

Use this field to enable the user to make a call to an internal contact using a short or a prefixed extension.

When this field is enabled and the user dials the short digit extension of an internal contact using the dialpad or call logs or contact from a supported endpoint, Communication Manager routes the call using the Call Type Digit Analysis table, taking the location of the caller into account. This field also applies to incoming trunk calls. For example, users in an organization can use five-digit extensions to make calls to internal contacts. If a user dials 8-2249, Communication Manager maps the dialed number to 1212-848-2249 using the Call Type Digit Analysis table before routing the call.
