Analog telephony cards support businesses that still use analog telephone lines for primary access to PSTN. The cards have 2-24 analog ports. This allows up to 24 simultaneous PSTN calls.

Their modular design gives you the option to choose between interchangeable FXO or FXO modules to create your own channel requirements.

The analog cards offer optional echo cancellation for superior audio quality and reduced CPU usage for optimized system performance.

All the cards work seamlessly with Asterisk, FreePBX, PBXact and are compatible with most motherboards and servers.
