Product details

OpenVox VoxStack Series 3G (WCDMA) Gateway is the first open-source Asterisk-based 3G VoIP gateway solution for SMEs and SOHOs. With a user-friendly GUI and a unique modular design, users can easily configure their customized gateway. Secondary development can also be carried out via AMI (Asterisk Management Interface).

There are three 3G gateway models in the VoxStack series: VS-GW1202, VS-GW1600, and VS-GW2120. The new modular VS-GW2120 Series 3G gateway can accommodate up to 11 GSM gateway modules, supporting 4 to 44 3G/UMTS channels and 3 Ethernet ports, and is developed to interconnect a wide selection of codecs, including G.711A, G.711U, G.729, G.722, G.723, G.726 & GSM. With 3G connectivity to the VoIP gateway, it helps quickly reduce telecommunication expenses and maximize savings. Thanks to its unique design, the VoxStack gateway supports hot-swapping SIM cards and 3G modules. Users can simply add or remove modules for expansion or hardware replacement. Each 3G gateway module runs an independent Asterisk system.

The VoxStack gateway is equipped with a LAN switch card that enables stackability during hardware upgrades. It supports sending and receiving SMS, bulk sending, and SMS-to-email conversion. 3G gateways use the standard SIP protocol and are compatible with IMS/NGN platforms, IPPBX, and SIP servers, supporting most VoIP platforms such as Asterisk, Elastix, 3CX, FreeSWITCH, Broadsoft, etc.
