Title: Proton VoIP: Privacy-First Business Phone System for the Proton Ecosystem

Category: General Ideas / Proton Business

Proton currently offers a strong privacy-focused ecosystem—Mail, Calendar, Drive, VPN, Pass, Meet, Lumo—but lacks a critical piece for business customers: a phone/voice service.

This post consolidates several existing requests (virtual phone numbers, VoIP calling, PSTN integration with Meet) into a single, cohesive product proposal: a privacy-first business VoIP system that would serve as an alternative to commercial providers like OpenPhone/Quo, RingCentral, Nextiva, and Google Voice Business.

Proposed Core Features:

Dedicated virtual phone numbers (local and toll-free, multiple countries)
Inbound and outbound calling via desktop, web, and mobile apps
SMS/MMS messaging with end-to-end encryption where possible
Voicemail with AI-powered transcription
Call recording (manual and automatic) with encrypted storage
Multi-level auto-attendant / IVR for call routing
Ring groups and call queues for teams
Shared numbers and inboxes across team members
Centralized billing and administration for Business plan customers
Integration with Proton Mail, Proton Calendar, Proton Meet, and Proton Contacts

Why This Matters:

Current VoIP providers require handing business communication data to third-party corporations with surveillance-based business models. Google Voice Business, for example, ties phone metadata to Google's advertising ecosystem. OpenPhone/Quo, RingCentral, and Nextiva offer solid features but operate under U.S. jurisdiction with standard data-retention policies.

A Proton VoIP service would be the only option on the market combining full business telephony features with end-to-end encryption, Swiss jurisdiction, and zero-access architecture. No privacy-focused equivalent exists today.

Target Audience:

Proton Business plan customers needing a complete communication suite
Privacy-conscious professionals and small businesses currently fragmenting tools across multiple providers
Users on existing UserVoice threads requesting virtual numbers, VoIP calling, and PSTN integration with Meet

Existing Demand on UserVoice:

This request consolidates and expands on multiple prior posts:

"Virtual Phone Number by Proton / Phone Number Alias & Masking"
"VoIP" (standalone calling request)
"Unified Proton eSIM & VoIP Feature"
"Proton Meet: PSTN Calling"

While those posts address individual needs, none cover the full business phone system feature set requested here. This post represents the consolidated use case of a paying Business customer who needs a complete, privacy-first phone solution within the Proton ecosystem.
