Frequently Asked Questions

What is UCaaS and why are Indian businesses switching to it?

UCaaS (Unified Communications as a Service) replaces traditional PBX phone systems, separate video conferencing tools, and siloed chat apps with a single cloud platform. Indian businesses switch because: (1) reduced cost vs EPABX hardware + maintenance, (2) better remote work support, (3) single vendor for all communication needs, and (4) easier IT management.

Can UCaaS replace a traditional EPABX phone system in an Indian office?

Yes — Zoom Phone, Teams Phone, and RingCentral all provide Indian PSTN numbers, IVR, call queues, and all features of a traditional EPABX. We handle number porting from existing EPABX, installation of IP phones or soft clients, and staff training as part of UCaaS migration.

Which UCaaS platform works best for Indian businesses with power outages?

UCaaS with mobile apps (all platforms listed) allows employees to continue taking calls on mobile data during power outages. Zoom Phone and Teams Phone automatically route calls to mobile app when the desk phone is offline. We configure call forwarding rules for power-outage resilience.

Upgrade your office communication to UCaaS — consultation, migration from EPABX, and training included.
