A Cloud PBX replaces your on-premise phone system with a hosted equivalent — calls, extensions, voicemail. UCaaS goes further by unifying voice, video conferencing, team messaging and file collaboration into a single platform with one login, one app and one admin console. The key difference is that UCaaS treats all those channels as native — not separate products bolted together.

In most cases yes — number porting is supported by all major UCaaS providers listed here, including DDIs (Direct Dial In numbers), toll-free numbers and geographic numbers. The timeline is typically 7 to 21 working days depending on your current carrier. We flag any provider with porting restrictions during the matching process.

Most platforms listed here integrate with both. Microsoft Teams Direct Routing and Operator Connect allow you to add enterprise calling directly into Teams without leaving Microsoft's ecosystem. Alternatively, platforms like Zoom Phone, Webex and RingCentral work alongside both M365 and Google Workspace with native calendar, contacts and presence sync.

We confirm data residency with every unified communications vendor before listing. All platforms here offer Indian data centres for call recordings, meeting replays and message history — with Data Processing Agreements aligned to DPDP Act 2023 requirements. If this is a hard requirement, flag it in the lead form and we will filter to providers with documented in-country storage.

For a cloud-only deployment with no number porting, most providers can provision users within 24–72 hours of contract signature. Full migrations including number porting, hardware (IP phones, conference room systems) and CRM integration typically take 2–6 weeks. We help scope the migration timeline during the matching process so there are no surprises.
