ringfusion competitors and assessment
Company assessmentDirect peers
- RingCentral: RingCentral is the category-leading pure-play cloud UCaaS/VoIP provider for businesses of all sizes, offering cloud PBX, SIP trunking, contact center, and video — directly overlapping with Ringfusion's product mix, pricing tiers, and target SMB-to-enterprise customer base.
- Ooma: Ooma offers cloud VoIP, SIP trunking, and virtual fax services targeted at small businesses and distributed enterprises — closely aligned with Ringfusion's small-team and enterprise tiers and channel-led distribution.
- Grasshopper: Grasshopper provides virtual cloud phone systems tailored to solopreneurs and small businesses, with similar ease-of-use positioning and tiered pricing that targets the same small-team segment as Ringfusion's Basic plan.
- Nextiva: Nextiva delivers cloud-based business phone systems, SIP trunking, and unified communications primarily to SMBs, with tiered pricing and 24/7 support comparable to Ringfusion's Basic/Business/Enterprise plans.
- Dialpad: Dialpad sells AI-augmented cloud business phone systems and UCaaS to SMB and mid-market customers, competing head-to-head with Ringfusion on cloud voice, mobile/desktop apps, and tiered monthly subscriptions.
- Vonage (Ericsson): Vonage, now part of Ericsson's Enterprise Wireless Solutions, provides cloud communications, SIP trunking, and UCaaS across SMB and enterprise segments — a direct overlap with Ringfusion's entire portfolio.
- 8x8: 8x8 provides cloud voice, video, chat, and contact center as a unified platform to SMB and enterprise customers, mirroring Ringfusion's hosted VoIP + SIP trunking + video meetings offering against a similarly broad size-tier customer base.
Broad incumbents
- Microsoft Teams Phone (Operator Connect / Direct Routing): Microsoft Teams Phone is the telephony capability built into the Teams collaboration platform; Ringfusion integrates with it as a partner, but Microsoft itself competes in the same cloud voice category for enterprise customers.
- Zoom (Zoom Phone): Zoom Phone is the VoIP/UCaaS arm of Zoom, bundled with the dominant video meeting platform and aimed at SMB through enterprise — overlapping with Ringfusion's cloud phone and video meetings offering but from a much larger installed base.
- Cisco Webex Calling: Cisco Webex Calling provides cloud PBX, UCaaS, and voice as part of the broader Webex collaboration suite — Ringfusion offers a co-managed Webex Calling service alongside its own PBX, and Cisco competes broadly in the same category.
