Digital Telephony Cards

TE100 Digital Cards

Sangoma’s TE131, TE132, TE133 and TE134 single span digital cards are designed for voice application with Asterisk, FreePBX and PBXact phone systems.. The TE13x utilizes state of the art technologies to support T1/E1/PRI environments that require a high-performance, cost effective digital telephony interface card. The TE13x family of cards have the ability to create a seamless network, interconnecting traditional telephony systems with Voice over IP technologies.

TE133 and TE134 model cards feature Octasic-based hardware echo cancellation that is built in to the cards, removing the task of echo cancellation from the systems CPU and increasing overall system performance and call quality. TE131 and TE132 model cards are for environments that do not require hardware-based echo cancellation, instead relying only on software echo cancellation.

Digital Card Applications


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.


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.
