Russian developer and manufacturer of Alvis computer-telephony gateways. On the market since 2000.
GarantPlus has been working since 2000 in computer-telephony systems: development and deployment of embedded SIP/E1 gateways, Asterisk-based software, autonomous base-station systems and SORM complexes.
In 2003–2006 the company was the exclusive Russian distributor and the sole development center for Odin TeleSystems Inc., leading the creation of SORM-1 complexes for mobile operators. In 2011 the business fully separated: GarantPlus licensed Odin's hardware designs and became an independent manufacturer.
Today GarantPlus is a fully Russian company with no foreign dependency. We design the circuitry, PCBs, enclosures and software for the Alvis-GW-2E1 gateways and control contract manufacturing. The equipment is certified (SSS certification system).
Over 1500 clients across Russia — from telecom operators and industrial enterprises to state corporations and defense-sector organizations.
