Analog Telephony Cards

A400 Telephony Cards

The Sangoma A400 analog telephony card is our high density analog card from two (2) to 24 ports for Asterisk, FreePBX and PBXact phone systems. That’s up to 24 PSTN calls all on a single PCI Express slot.  The modular nature of the cards allows you to mix and match between FXO and FXS interfaces, giving you the exact port configuration you need.

The base A400 telephony card provides from 2-12 analog ports using dual channel interface modules and is expandable up to 24 ports by adding daughterboards and the Remora backplane system

With hardware echo cancellation options, compatibility with most commercial grade servers and Linux operating systems and with a lifetime warranty, customers trust in Sangoma to deliver value based telephony solutions.

Which type of module do I use?

  • FXS Ports are used to connect analog telephones and fax machines. They are also used to connect to the FXO ports of an analog phone system. They provide ring voltage to FXO devices.

Analog Card Applications

PSTN-TRUNKING

Use inside a server of your choice, powered by Linux/Windows, to create a SIP-TDM Gateway to allow IP-PBX to route calls to traditional PSTN.

SIP-TRUNKING

Use inside a server of your choice, powered by Linux/Windows, to create a SIP-TDM Gateway with your  legacy analog based PBXs to replace expensive analog line connections with SIP trunking to allow reduced call costs, reduced line rental, and bring extra flexibility and disaster recovery.

FAX AND LEGACY GATEWAY

Use our Sangoma cards in your choice of hardware to connect legacy analog equipment like fax machines, door-bells or analog phones to your IP-based network.

CALL RECORDING

Monitor and record telephone conversations for lawful call interception. Use your choice of software, including Sangoma’s own TDM SDK dedicated for call tapping.
