Description

Sangoma PSTN cards – Flexible telephony solution for analog and digital networks

Sangoma PSTN cards provide a reliable and powerful interface for companies that need a connection between traditional telephone networks (PSTN) and modern VoIP solutions. They support various network technologies such as analog lines (FXS/FXO), BRI (Basic Rate Interface), PRI (Primary Rate Interface), SS7, E1/T1/J1 and GSM. This makes them ideal for use in companies, data centers and carrier environments.

Versatile configurations for maximum flexibility

The cards are available in several variants – from pure analog cards to hybrid models that combine BRI or PRI connections with analog interfaces. This enables easy integration into existing systems and ensures a smooth migration to VoIP technologies.

Optimum voice quality with optional echo cancellation

For maximum voice quality, all Sangoma PSTN cards are available with optional “Telco Grade” echo cancellation. This eliminates background noise and ensures crystal-clear call quality – even in complex network infrastructures.

Robust and cost-effective solution for businesses

With an outstanding price-performance ratio, Sangoma PSTN cards are a durable and reliable solution for companies that want to continue to rely on traditional telephony or operate hybrid communication environments. They enable smooth integration into existing systems without the need for expensive hardware upgrades.
