CallTower Tech Stack

Cloud communications and contact center platform for enterprise resellers

Telecommunications South Jordan, Utah 201–500 employees Founded 2002 Privately Held

CallTower operates a multi-tenant cloud communications platform anchored in Microsoft Teams Operator Connect, Webex, and Zoom Phone, with contact center capabilities (Five9, Webex Contact Center, Genesys). The stack reveals a reseller-first GTM: aggressive hiring in sales (6 roles, mostly senior) paired with active projects around rebiller/reseller channel expansion and adoption, while engineering (5 roles) focuses on voice bots and AI tooling. Pain points cluster around reseller productivity, proposal workflows, and compliance — typical friction when scaling a channel business.
