What Sothis Tecnologia E Servicos De Telecomunicacoes Ltda does

Sothis Tecnologia E Servicos De Telecomunicacoes Ltda, doing business as Sothis Telecom, is a privately held Brazilian telecommunications carrier licensed by ANATEL since 2009 to provide voice (STFC, VoIP, SCM) and data services (SCM, LAN-to-LAN, dark fiber) across 23 Brazilian states. The company operates its own fiber optic backbone and delivers services through a portfolio centered on PABX na Nuvem (a cloud-based IPBX with URA, DAC, call recording, conference, and custom routing), PABX IP, Link Dedicado (dedicated symmetric internet with fixed IP), Banda Larga Empresarial, and Banda Larga Residencial, plus add-on offerings such as dark fiber and virtual numbering. Technology is conventional IP-based voice and data: VoIP and SIP trunking delivered over proprietary fiber, with a cloud-managed PABX front end that eliminates on-premise hardware for customers.

The business model is subscription-recurring on monthly billing cycles, with consultation-based enterprise pricing rather than public rate cards. Sothis serves three horizontal segments: enterprise/business customers (primary) requiring cloud telephony, dedicated links, and multi-location IP communications; SMBs needing business broadband with static IPs; and residential heavy users on fiber. Go-to-market is sales-led, combining a direct enterprise sales force with a reseller/partner channel program for telecom and IT resellers, supported by content marketing (blog), organic social, email, and a Hubsoft-integrated mobile app for self-service (billing, contracts). The company maintains offices in São Paulo (HQ and secondary), São Bernardo do Campo, and Miami, and is LGPD-compliant with a designated Data Protection Officer.
