Numbering Plan
The numbering plan establishes the “dial plan” that will be used for the X-50 system. It defines the start extension
number (101) and the ending extension number (125), as well as the day and night operator extension or extensions.
In addition, the X-50 includes one FXS (Single Line - analog - Telephone) which has a default number of 125 and the
number to be dialed to ring the operator (0); all of which can be customized.
The SIP Authentication area is where the extension telephone numbers and passwords are established. These
numbers are used by the SIP telephone endpoints to authenticate to the X-50 system. It is important to keep in
mind if this system is going to be part of a larger voice network, the whole network must have one unified numbering
plan. For example, a system in Boston may have extensions numbered 1001 - 1025, in Chicago 1501 - 1525, Las
Vegas 2001 - 2025 and in San Francisco 3001 - 3025, etc. This will allow an extension to dial 4 digits (3 digits number
plans will also work) and speak to someone at a different location. For example, someone in Boston dials 2021 and
speaks to an extension user in Las Vegas without using a telephone line. Tables “Suggested 4-Digit Numbing Plan” on
page 92 and “Suggested 3-Digit Numbing Plan” on page 93 show some suggestions extension numbering plans.
Note:
When entering a new numbering plan do not use 311, 411 and 911 as extension numbers.
