2 D IAL P LAN The NBX system’ s dial plan determines how the system handles calls. It defines the set of destinations that the system can reach, how to get to these destinations, and which telephon e numbers to dial to reach these destinations. This chapter provides information about understan ding, developing, and managi ng the dial plan . It co[...]

28 C HAPTER 2: D IAL P LAN Dial Plan Concepts and Overview The dial plan configuration file is a n ASCII text file that implements the dial plan and specifies pretranslation (d igit manipulation). The system is shipped with several defa ult dial plan configuration files, typically , a 3-digit and a 4-digit file for each suppor ted country . The dia[...]

Dial Plan Concepts and Overview 29 Call Process Flow The dial plan configuration file is a key component of inbound and outbound call processing. The dial plan tables in the configuration file process incoming calls in this order: 1 Incoming Dial Plan T able 2 Pretranslator T able The dial plan tables process outg oing calls in thi s order: 1 Inter[...]

Dial Plan Concepts and Overview 31 The system is shipped with several default dial plan configuration files, typically , a 3-digit and a 4-digit file for each country that is supported. In addition, the file samples.txt contains several examples that illustrate how you can configure the dial plan co nfiguration file to control how the system manage[...]

32 C HAPTER 2: D IAL P LAN Y ou can route incoming calls to the Auto Attendant port, and you can instruct the Auto Attendant to route these calls to any in ternal or exter nal number . CAUTION: If you configure th e Auto Attendant so that it can access any external number , you risk the possibilit y of toll fraud. Y ou can reduce the possibility of[...]

Dial Plan Concepts and Overview 33 The NBX system a pplies any Class of Ser vice restrictions that are associated with the user's telephone to determine whether to make a call. The system also uses any pretranslator that a device uses and performs any requir ed digit manipulation operations before it actually transmits the digits on the Analog[...]

34 C HAPTER 2: D IAL P LAN Dial Plan T ables Dial plan tables contain information that controls how the system r outes calls. Each dial plan configuration file consists of at least thr ee dial plan tables. This section discusses these topics: ■ Dial Plan Command Format ■ Internal Dial Plan T able — Must be table ID 1 ■ Incoming Dial Plan T [...]

Dial Plan Tables 35 Figure 2 Dial Plan Command Format Ta b l e 6 describes each field of a dial plan command.

36 C HAPTER 2: D IAL P LAN If a new entr y in the Internal table ap pears not to work, it is possible that the system is using an entry from the Least Cost table instead. T o avoid such conflicts, you can accomplish least cost routing using only the Internal table. 3Com strongly recommends that, to keep the dial plan as simple as possible, you use [...]

Dial Plan Tables 37 would collect all 4 digits of th e extens ion. If the caller dials fewer than the Min number of d igits, the system times out in 20 seconds. Example: If Digits = 2, Min = 4, and Max = 4, the syste m knows that if the first digit is 2, it must collect no less than 4 and no more than 4 dig its before making the call routing decisi[...]

38 C HAPTER 2: D IAL P LAN Example: Y ou can assign the company’ s Vice President of Finance to a group that you name the All Privileges Group .

An Incoming dial plan table typically has a mor e r estricted list of[...]

40 C HAPTER 2: D IAL P LAN Adding New Dial Plan T ables If you are sharing the system with another company or group and want to control calls dif f erently at the tw o sites, you can add a fourth table. Example: Y ou assign one exten sion range to Company A and a different range to Company B. The fourth tabl e controls the extension range for Compa[...]

Dial Plan Pretranslators 41 Example: Say that the DDI/DID telephone numbers range from 508-555-4200 through 508-555-4299. The teleph one company sends you the last 4 digits of the total telephone number . Inter nally , you want to use extensions 2000 through 2099. Y o u can define a pretranslator to: ■ Remove (stripLead) the first two d igits of [...]
