Digium hardware extends the power of Asterisk to the Public Switched Telephone Network (PSTN) and beyond. Digium is the leading manufacturer of analog and digital interface cards, voice compression modules, redundancy solutions, and IP media gateways for use with the Asterisk open source communications engine.
IP Media Gateways
Digium’s VoIP gateways are industrial grade appliances designed to bridge the gap between TDM (T1/E1/PRI) and IP networks. Built on a powerful combination of the Asterisk open source communications engine and a state of the art embedded platform, the gateways provide the best value for Asterisk connectivity.
Digium offers 2 gateway models: the G100 appliance and the G200 appliance.
Analog Telephony Devices
Connect your Asterisk system with analog lines, phones, fax machines and other gear with Digium’s rock solid analog interface cards.
Digium’s super-reliable digital line cards connect Asterisk-based communication systems to T1, E1, J1 and ISDN-BRI interfaces. Digium digital interface cards can be used to connect Asterisk with service from telephone carriers or to interface with legacy communications equipment. All Digium digital cards include a built-in CSU/DSU and may be connected directly to the E1/T1 physical interface without the need for additional hardware.
1 T1/E1/J1 Port
2 T1/E1/J1 Ports
4 T1/E1/J1 Ports
4 S/T Ports
8 Port T1/E1/J1 Card, PCI Express
Up to 8 analog or digital BRI ports.
Voice Compression Cards
Digium’s voice compression cards enhance the capabilities of Asterisk in VoIP and Hybrid Environments. TC cards are transcoders; they convert phone calls from one encoding format to another, usually to save on bandwidth. Our voice compression cards are both capable of compressing/decompressing 120 channels of G.729 or 92 channels of G.723.1.
The R-Series appliances allow Asterisk users and integrators to build fully redundant communications systems. The R-Series devices handle the physical redirection of PSTN circuits in the event of a catastrophic hardware or software failure. Tightly integrated with monitoring and resource management software, the R-Series can switch PSTN traffic within seconds of a service interruption. A pair of Asterisk-based servers cross-connected through an R-Series appliance can achieve 99.99% availability at a fraction of the cost of other redundant communications solutions.
Digium offers 2 failover models: the analog R800 appliance and the digital R850 appliance.
