An internal phone system for managing and routing calls in an enterprise is called a PABX (Private Automatic Branch Exchange) system. It functions by joining internal phone lines to the external phone network, enabling users to make calls from a single access point to both external and internal parties within the company.

In addition to saving money on phone bills, PABX systems also improve communication with features like voicemail and call forwarding, are more scalable to meet the needs of expanding enterprises, and provide centralized control of telephony resources.

Unlike PABX systems, which handle phone calls, intercom systems are mostly used for internal communication. An intercom system is a communication device that allows direct audio or video communication between different rooms or locations within a building

There are many different kinds of intercom systems, such as IP-based intercoms, video intercoms, wired intercoms, and wireless intercoms. The ideal option will vary depending on the building’s size, features that are wanted (audio-only vs. audio-video), and financial constraints. 

Intercom systems are essential for increasing security since they let employees or residents confirm a visitor’s identification before allowing them entry. In the event of an emergency or questionable activity, they also make it easier to communicate with security staff. 

Indeed, a lot of contemporary intercom and PABX systems have integration features that let internal and external parties communicate easily. Features like dialing extensions from the intercom system or utilizing intercom functions from phones linked to PBXs are made possible through integration.

In order to guarantee the best possible performance and longevity, it is advised that PABX and intercom systems undergo routine maintenance checks. Various factors, including usage intensity, climatic conditions, and manufacturer guidelines, might affect frequency.
