Quobis Phone

Corporate-grade telephony end-point for every user, device and workspace.

Talk to an expert

A universal endpoint for your corporate telephony.

One softphone that works on top of any voice infrastructure — your PBX, your SBC, your carrier network — without replacing anything unless you choose to. Browser, as Microsoft Teams App, desktop or mobile. Your users get a modern corporate phone; your IT team keeps full control.

Quobis Phone is built on Quobis Communications Platform and designed to coexist with your current infrastructure — or progressively replace it: deploy it alongside existing endpoints, integrate it into hybrid architectures, and evolve your telephony at your own pace — not your vendor’s.

Quobis Phone UI is customizable look & feel with your brand’s corporate identity.

Everything your users need, out of the box

Internal and external calls

Full PSTN connectivity, internal extensions, multi-party conferencing, video calls and chat — all from a single interface.

Compatible with your numbering plan

Preserves existing numbering schemes, short numbers and dial plans. Users keep calling the way they always have.

Designed for everyone.

An intuitive interface that requires minimal training, suitable for any user profile — from front-desk staff to field workers to executives.

Separate corporate and personal spaces.

Corporate and personal directories and planners remain independent, protecting both the organization’s data and the user’s privacy.

One identity, any device.

Your corporate extension follows you seamlessly — office desktop, laptop at home or personal mobile (BYOD). Native iOS and Android apps with push notifications ensure you never miss a call, even in the background.

Ready for professional telephony.

Supports call transfer, hold, BLF, multi-line and other advanced PBX features out of the box — no custom development needed. Quobis Phone exposes the full capabilities of your existing infrastructure through a modern, unified interface.

Core capabilities

Built to fit your infrastructure — not the other way around

Universal infrastructure compatibility.

Integrates with any PBX, SBC, SIP trunk, carrier network or numbering plan — regardless of vendor or generation.

Hybrid architecture support.

Deploy alongside other vendors’ endpoints and coexist within complex, multi-site communication environments.

Zero-footprint access.

Browser-based calling with no client installation, IT eliminates the need for updates across thousands of devices, enabling immediate service deployment.

Multi-platform endpoint.

Also available as desktop, mobile app or Microsoft Teams app for scenarios that require a persistent client.

Centralized endpoint management.

Provisioning, updates, policies and service evolution managed centrally — even across hybrid deployments.

Open standards foundation.

Built on SIP and WebRTC, avoiding proprietary lock-in at the protocol, codec or interface level.

Future-proof

Technological sovereignty by design

Quobis Phone is European technology with no dependencies on non-EU technology stacks. Every component of the value chain — data, software, operations and infrastructure — can remain under your organization’s governance.

This makes Quobis Phone a natural fit for public administrations, regulated industries and any organization aligned with European digital sovereignty strategies.
