Turn Every Business into a Connected Enterprise
One cloud-native IMS platform for operators to deliver hosted PBX, enterprise voice, unified communications, conferencing, and contact center — all multi-tenant, all API-driven, all carrier-grade.
Without a unified cloud PBX platform, enterprise voice systems operate at critical inefficiency.
Legacy on-premise PBX systems are aging — expensive to maintain, impossible to scale, and lacking modern features
Enterprise branch voice systems are fragmented — each location runs its own isolated phone system
Operators lack differentiated enterprise voice and UC value-added services to compete with OTT players
Enterprises demand unified communications — IVR, conferencing, recording, voicemail — but get piecemeal solutions
No true multi-tenant enterprise voice platform — operators cannot efficiently serve thousands of business customers from one system
Integration between voice, CRM, and business applications is missing — voice becomes a siloed utility
Migration from legacy TDM/PSTN to all-IP IMS-based voice is complex and risky without the right partner

Frequently Asked Questions
How does ZBensoft's multi-tenant architecture work?
Our platform uses a true multi-tenant architecture — each business customer gets a logically isolated tenant with its own numbering plan, dial plan, auto attendant, users, and policies. Tenants share the same IMS core and application server infrastructure but with complete data and configuration separation. Operators manage all tenants from a single admin portal.
Can enterprises keep their existing phone numbers?
Yes. The platform supports full number porting and management — including DIDs, toll-free numbers, and international numbers. We provide automated number provisioning, LNP (Local Number Portability) workflows, and integration with major number providers and exchanges.
What endpoints and devices are supported?
The platform supports the full range — IP desk phones (Poly, Yealink, Cisco), SIP softphones, our own white-label soft client (iOS, Android, Windows, Mac, WebRTC), analog phones via ATAs, and SIP trunking to existing on-premise PBXs. We also provide WebRTC SDKs for embedding voice directly into enterprise web and mobile applications.
