Digium's family of IP Phones for Asterisk are the first on the market built specifically for use with Asterisk and Asterisk-based systems. All models include HD audio and plug-and-play deployment at a price that fits any budget. With multiple line appearances, context-aware soft keys, and advanced applications that integrate directly with Asterisk features, Digium phones offer a better user experience than any other phone on the market. These IP phones are also ideal to use with Digium's Hosted VoIP solution, based on Asterisk.
A VoIP Gateway allows you to convert between a legacy telephony connection, such as E1/T1/PRI and a modern VoIP connection using SIP. This is known as "digital gateway" because the voice media is converted between a digital TDM connection and a VoIP connection. The conversion can go from SIP to TDM, TDM to SIP or even SIP to SIP for the purposes of failover or transcoding. In a TDM-to-SIP deployment, the gateway significantly reduces operating costs by connecting a legacy business phone system with dynamic SIP trunking services. SIP-to-TDM deployments use the gateway to connect a modern SIP communications system with T1/E1/PRI service from legacy carriers. There are many applications for VoIP media gateways.
Digium offers a full line of high quality analog and digital interface cards to connect your IP PBX, IVR, VoIP Gateway, or custom telephony solution to the public telephone network. Digium also has hybrid cards, voice compression cards, modules, and accessories built specifically for Asterisk.
Digium's dual span digital interface cards support 48 (T1 / J1) or 60 (E1) connections to PSTN trunks over two spans (digital circuits). Built exclusively for use with Asterisk and Asterisk-based communications systems, the dual span cards provide the best value in digital connectivity.
Digium's quad span digital interface cards support 96 (T1 / J1) or 120 (E1) connections to PSTN trunks over four spans (digital circuits). Built exclusively for use with Asterisk and Asterisk-based communications systems, the quad span digital cards provide the best value in digital connectivity.
Digium’s TE820 Octal-Span digital card is built exclusively for high-density Asterisk® applications that require high-performance, cost effective digital connectivity.
Using Digium's digital hardware, open source Asterisk PBX software, and a Linux PC, users can create an intelligent telephony environment that includes all the sophisticated features of a high-end PBX platform.
The Hx8 Series are versatile devices used for connecting to the PSTN. This is accomplished with analog lines connected to trunk (FXO) interfaces, analog handsets connected to station (FXS) interfaces, and digital lines connected to ISDN BRI interfaces.
The TC400B is a bundle of the half-length, low-profile PCI-2.2 compliant TC400P base card and the TC400M voice processing module. The TC400B is designed to handle, in dedicated DSP resources, the complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software.
The TCE400B is a bundle of the half-length, low-profile PCI-Express x1 TCE400P base card and the TC400M voice processing module. The TCE400B is designed to handle, in dedicated DSP resources, the complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software.
For Asterisk users connecting to the PSTN, echo with the voice communication is possible and can be managed effectively with echo cancellation modules from Digium.
The S400M FXS module allows 800 Series or 2400 Series analog cards to terminate four (4) analog stations per module. The X400M FXO module allows 800 Series or 2400 Series analog cards to terminate four (4) analog lines per module.
The S110M FXS module allows 400 Series or 800 Series analog cards to terminate a single analog station per module. The X100M FXO module allows 400 Series or 800 Series analog cards to terminate a single analog line per module.
FXS modules provide ringing voltage and battery to telephones or handsets and require substantial amount of 12V DC power in order to operate properly. The PCI interface on motherboards cannot provide sufficient quantities of this voltage necessary to ring 4, 8 or 24 modules.
