Digital telephony cards
Digital telephony cards come with 1, 2, 4, 8, and 16 ports of T1/E1/J1 optimized for voice and data applications. This allows up to 480 simultaneous voice calls or 32,768 Mbps of full duplex data.
They support the following protocols: PRI, BRI, and CAS MFCR2.
Most of the digital cards have built-in echo cancellation for superior audio quality and reduced CPU usage for optimized system performance.
These cards are designed to work with Asterisk, FreePBX, and PBXact. Thanks to the wide protocol support, API integrators often choose these digital cards.
