Description

The Excelltel CS+424 is an analog PABX (Private Automatic Branch Exchange) system designed for small to mid-sized offices requiring basic internal communication and external call management. It supports up to 4 CO lines and 24 analog extensions, offering a reliable, low-maintenance solution for organizations with traditional telephony requirements.

This model includes features such as automated call routing through a built-in DISA system, flexible call transfer and forwarding options, internal conferencing, and call monitoring. It supports caller ID and offers customization through programmable extension numbers and class-based call restrictions.

The CS+424 is compatible with standard single-line analog telephones and offers additional features when used with Excelltel’s own digital keyphone units. With built-in memory protection, lightning resistance, and optional battery backup, the system ensures continued operation during brief power outages or surges.

Due to its analog nature, it is best suited for businesses not reliant on VoIP or IP telephony and that prefer a straightforward, cost-effective communication system.
