Advanced Excelltel Px400s IP PBX System for Businesses

An IPPBX stands for Internet Protocol Private Branch Exchange. It is an enterprise-grade phone system that uses IP networks, such as your office LAN or the internet, to manage and route voice calls, rather than traditional analog phone lines or circuit-switched networks. Unlike a traditional PBX that requires dedicated copper wiring and supports only analog phones, an IPPBX converges voice and data on a single network. It supports IP phones, softphone apps, and analog phones simultaneously.

FXS and FXO are two different types of analog ports, and understanding the difference is essential for setting up your system correctly. FXS stands for Foreign Exchange Station. The "S" stands for Station, meaning it connects to your internal station devices such as analog desk phones, fax machines, cordless phones, or door entry systems. An FXS port provides dial tone, electrical power, and ringing signals to the connected device. FXO stands for Foreign Exchange Office.

The WAN0 port connects to your router or switch for internet access and remote management. The LAN port is optional for connecting IP phones directly. The 4 FXO ports connect to your telecom provider's analog lines using RJ11 cables. The 4 FXS ports connect to your analog desk phones, fax machines, or cordless phones using RJ11 cables. A 16GB TF card comes pre-installed for call recording. Plug in the 5V DC power adapter to power on the device.

With a 4-in, configuration, the PX400S is ideal for small to medium-sized businesses or branch offices that need one to two outside lines and up to four analog extensions. In addition to the analog ports, it supports up to 128 SIP users, so your employees' IP phones or softphone apps can also register to the system, enabling unified internal and external communications.
