Networking
You can connect several KX-TD500 Systems to make a PBX (private branch exchange), network, which lets users share a certain number of outside lines for making telephone calls through T1 lines.


 
Modular Design
Easily expand from 8 phones and 8 lines to as many as 448 extensions and 192 central office lines by adding expansion cards. The system can be installed in a one, two, or three shelf configuration, providing economical expansion from 192 ports (1 cabinet), to 384 ports (2 cabinets), to 512 ports (3 cabinets).

Non-Blocking Architecture
Every phone connected to the system will always have a dial tone - even during the busiest times of the day, ensuring that every call can be placed in a timely manner.

Automatic Route Selection
 
Automatically routes outgoing calls to the most cost-efficient long distance carrier within your network based on time-of-day, day-of-week and call destinations.

Station Message Detail Recording
A printed record of every extension's outgoing and/or incoming calls is available with the connection of an optional printer, allowing you to track telephone expenses and help reduce telephone abuse.

Phantom Extensions
Incoming calls and internal transfers can be sent to a phantom extension, which will ring every phone with that extension button. This is an ideal arrangement for the sales staff, technical support staff or other specific group to identify calls intended for their response. Up to 448 phantom extensions can be assigned.

Uniform Call Distribution
Evenly distributes incoming calls to operators or agents logged into a specific UCD group, such as at a travel office or customer support center, for example. People within a UCD group have the capability to temporarily remove themselves from the group, and four different outgoing messages can be recorded and played in a cycle

System Speed Dialing
Program frequently called numbers into the system for quick and easy dialing from any phone in the system.

Toll Restriction
Control long distance calls by restricting certain extensions from accessing specific area codes or exchange codes.

Direct Inward Dial (DID)
With the addition of an optional expansion module, the system can be connected to DID lines provided by the telephone company, so incoming calls will be directed to a specific extension, alleviating the need for an operator or attendant.
