We support any PBX system that is SIP-enabled. This includes popular VoIP IP-PBX’s like Asterisk, FreePBX®, Trixbox, Switchvox, PBX in a Flash, Elastix, Bluebox, FusionPBX, 3CX, sipXecs, Go Auto Dial, Vicidial, Thirdlane and more. Many traditional PBX manufacturers also support SIP trunking with their latest software releases. These SIP-capable PBX vendors include: Toshiba, Panasonic, NEC, Avaya, Cisco, Nortel, Intertel and others. For those systems that do not support SIP trunking, we support SIP-T1 gateway devices where it’s SIP-in and T1-out to the PBX. Examples of these types of gateways are the Digium G100 and G200 gateways. In addition, we fully support analog telephone adapters (ATAs) which can interface to legacy analog PBX’s and key systems. We recommend the Cisco SPA-2102 for a single port ATA interface and the Grandstream GXW400X series multi-port ATAs for interfacing with analog systems that require more than one line.
