What Appia Communications does
Appia Communications is a U.S.-based, privately held managed services provider of IP communications technology, founded in 2001 and headquartered in Traverse City, Michigan. Per its firmographic description, the company's value proposition centers on enabling customers to realize the benefits of IP technology at a cost lower than an in-house implementation—positioning it as a managed/outsourced alternative to direct UCaaS platform procurement.
Operationally, the brand operates within the broader CallTower, Inc. corporate structure (a Utah-incorporated entity headquartered in South Jordan, UT). Through that umbrella, Appia's service portfolio extends well beyond basic IP telephony to include Microsoft Teams calling and collaboration solutions (Operator Connect, Direct Routing, GCC High Teams), Cisco Webex Calling and Dedicated Instance, Zoom Phone, SIP trunking, cloud fax, dynamic E911, compliance recording, analytics, CRM integration, and CCaaS platforms (Five9, Genesys Cloud, Webex Contact Center, Zoom Contact Center). Value-added modules such as One Click Failover, voice spam blocking (via Mutare), Teams/Webex eSim, and CT Cloud Fax supplement the core stack.
The go-to-market is a managed services / reseller model: subscription-based recurring revenue on UCaaS and CCaaS platforms, professional services for migrations and integrations, and ongoing managed support. Distribution is via direct enterprise sales and channel/agency/MSP partner programs, serving customers across 80+ countries via the parent's 15 geo-redundant data centers. Target customers span healthcare, financial services, education, government, manufacturing, retail, and hospitality—though no Appia-specific named logos or case studies were disclosed. No pricing tiers, contract terms, ARR figures, or revenue disclosures are publicly available.

Appia Communications competitors and assessment
Company assessmentDirect peers
- RingCentral: Public UCaaS/CCaaS vendor offering cloud voice, contact center, and AI capabilities across multiple platforms. Direct competitor to CallTower for mid-market and enterprise UCaaS deals, with overlapping Microsoft, Webex, and Zoom partnership strategies.
- Genesys: Enterprise CCaaS and CX platform; a CallTower integration partner but also a direct competitor in larger contact center deployments where CallTower would resell Genesys.
- Five9: Public CCaaS pure-play and named CallTower partner. Competes in the contact center layer while also being delivered by CallTower, creating an overlapping sell where either party could win the enterprise.
- Dialpad: AI-native UCaaS and CCaaS provider selling cloud voice and contact center to SMB and mid-market. Comparable business model and target buyer profile, with stronger native AI messaging.
- Nextiva: Privately held UCaaS and CCaaS provider with broad vertical coverage. Direct competitor for SMB and mid-market voice and contact center deals.
- 8x8: Public UCaaS and CCaaS provider with global voice infrastructure and contact center offerings. Competes head-to-head with CallTower for enterprise and mid-market deals, particularly around Microsoft Teams integrations and CX.
Broad incumbents
- Vonage (Ericsson): Communications APIs and UCaaS provider acquired by Ericsson. Competes broadly in UCaaS and CPaaS and overlaps with CallTower on SIP trunking and global voice services.
- Cisco (Webex): Cisco Webex Calling, Webex Dedicated Instance, and Webex Contact Center are CallTower-integrated platforms; Cisco also competes directly for large enterprise communications deals.
- Zoom (Zoom Phone and Zoom Contact Center): Zoom Phone and Zoom Contact Center are both CallTower offerings and direct enterprise alternatives. As a platform incumbent, Zoom can route around CallTower by selling natively to enterprise customers.
- Microsoft (Teams Phone): Microsoft Teams Calling, Operator Connect, and Direct Routing are core CallTower offerings; Microsoft also sells Teams Phone natively and could compress CallTower's role over time.
