Scale indicators2 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Microsoft (Teams): Microsoft Teams Phone is one of the largest UCaaS offerings globally and a core platform CallTower integrates with via Operator Connect and Direct Routing. Microsoft is both a key partner and a broad incumbent competitor as it expands Teams' native calling capabilities.
• Cisco (Webex): Cisco Webex is one of the leading UCaaS/CCaaS platforms that CallTower resells and integrates. Cisco is simultaneously a strategic partner (CallTower sells Webex Calling) and a broad incumbent competitor that can sell Webex directly to enterprise customers.
• Five9: Five9 is a leading pure-play CCaaS provider serving large enterprise contact centers. While CallTower partners with Five9 as a reseller/implementer, Five9 is also a broader incumbent that competes for the same enterprise contact center deals CallTower pursues.
• Genesys: Genesys is a major CCaaS and customer experience platform provider serving large global enterprises. CallTower partners with Genesys Cloud, but Genesys also competes broadly for enterprise contact center transformations where CallTower positions its services.
• Zoom: Zoom is a major UCaaS and CCaaS platform provider (Zoom Phone, Zoom Contact Center) and a core partner of CallTower. Zoom represents both a platform CallTower resells and a broad incumbent that directly competes for the same enterprise communications wallet.

Direct peers

• Vonage: Vonage (acquired by Ericsson) offers UCaaS, CCaaS, and CPaaS solutions for businesses. Comparable to CallTower as a cloud communications provider for enterprises, with additional exposure to APIs/CPaaS that CallTower does not pursue.
• Nextiva: Nextiva is a UCaaS provider serving primarily SMB and mid-market customers with cloud voice, collaboration, and contact center solutions. Comparable to CallTower as a unified cloud communications provider, though more weighted toward smaller customer segments than CallTower's enterprise focus.
• RingCentral: RingCentral is the leading pure-play UCaaS provider offering cloud communications and contact center to enterprises and SMBs globally. It is the most direct competitive comparable to CallTower in enterprise cloud voice, though RingCentral competes on its own proprietary platform rather than reselling Microsoft/Cisco/Zoom.
• Mitel: Mitel provides cloud and hybrid business communications, including UCaaS solutions for enterprises and SMBs. Comparable to CallTower as a UCaaS provider serving enterprises with voice and collaboration, with a notable focus on hybrid cloud migrations from legacy PBX.
• 8x8: 8x8 provides UCaaS and CCaaS solutions to mid-market and enterprise customers, with an integrated platform for voice, video, chat, and contact center. It is comparable to CallTower as a unified cloud communications provider serving enterprise customers, though on its own proprietary stack.
