Description
The Sangoma A4 series analog telephony card has one (1) to four (4) ports and is compatible with phone systems such as Asterisk, FreePBX, and PBXact. A single PCI or PCI Express slot can support up to four PSTN calls. Because the cards are modular, you can mix and match FXO and FXS interfaces to create the exact port configuration you need. Single-channel interface modules provide 1-4 analog ports on the A4 series telephony card. Because of hardware echo cancellation options, compatibility with most commercial-grade servers and Linux operating systems, and a lifetime warranty, customers rely on Sangoma to deliver value-based telephony solutions.
