Question 1

What does Quobis do?

Quobis (Quobis Networks SL) is a telecommunications software vendor and systems integrator headquartered in O Porriño (Pontevedra), Spain. The company develops carrier-grade unified communications and real-time communication software that bridges legacy telecommunications infrastructure with web-based real-time communication technologies. Operating across Europe and internationally, Quobis functions at the intersection of application server software, session border controller (SBC) systems integration, and sovereign digital telephony. Its primary business model combines proprietary software licensing, managed software services, and specialized telecom engineering. Quobis solves the challenge telecom operators, contact centers, and regulated enterprises face when modernizing voice architectures, integrating browser and mobile calling into IP Multimedia Subsystem (IMS) and Private Branch Exchange (PBX) environments, and securing calling channels without replacing core legacy investments.

Question 2

What products, services and core capabilities does Quobis offer?

The core of Quobis's software portfolio is the Quobis Communications Platform, centered on the Quobis WebRTC Application Controller (WAC). This platform provides session management, media gateway coordination, and API and SDK exposure (JavaScript, iOS, Android, and C++) to embed voice, video, screen sharing, and messaging natively into browser, mobile, or enterprise applications. For enterprise collaboration, Quobis offers Quobis Phone—a sovereign softphone that connects directly to existing PBX and carrier infrastructure—and Quobis Phone for Microsoft Teams, which provides independent voice calling and PSTN access inside Teams without requiring Microsoft Phone System licenses. The company also supplies Quobis Collaborator, a complete web-based UCaaS application suite, and Quobis Click to Call, which routes incoming browser or app audio and video interactions directly into existing contact center automatic call distribution (ACD) workflows. Its security and network observability portfolio features Quobis VoIP Monitor for real-time voice signaling and media tracking, Quobis Caller Score for identity verification and anti-fraud scoring via CAMARA network APIs, and branded calling capabilities across RCS and native apps. Deployments support on-premises private infrastructure, cloud hosting (AWS or public clouds), and hybrid edge setups. Quobis also delivers managed SBC as a Service, professional engineering for Microsoft Teams Direct Routing, and consulting across open-source stacks (Kamailio, Asterisk, FreeSWITCH, Janus) and proprietary SBC architectures.

Question 3

What types of organizations are a good fit for Quobis?

Quobis is an optimal fit for European telecommunications service providers, public administrations, financial institutions, and contact centers seeking European digital sovereignty and granular control over communications infrastructure. It serves organizations with complex legacy telecommunications footprints—such as existing SIP trunks, PBX systems, and certified SBC hardware—that wish to modernize user endpoints or deploy WebRTC channels without replacing core investments. Organizations evaluating Quobis generally possess dedicated voice engineering personnel or seek specialized external engineering for Microsoft Teams Direct Routing, IMS integration, and open-source telephony. Conversely, small businesses desiring a plug-and-play, turnkey cloud PBX with bundled domestic calling plans, or organizations seeking consumer-facing CPaaS messaging with no custom infrastructure maintenance, will find Quobis overly specialized and engineered beyond standard administrative needs.

Question 4

Who are Quobis's main competitors and alternatives?

Quobis competes in the real-time communications, carrier softphone, and enterprise WebRTC gateway market. Its main alternatives include vendor-agnostic softphone providers, telecom application server vendors, and real-time WebRTC media platform specialists. Key competitors include Acrobits (a Sinch company), which provides white-label SIP softphones, Cloud Softphone, and SDKs for telecom operators and VoIP resellers; CounterPath, known for its Bria enterprise softphone suite and centralized provisioning; PortSIP, offering multi-tenant PBX software, WebRTC SBCs, and UC mobile and desktop clients; LiveSwitch (formerly Frozen Mountain), which supplies self-hosted and cloud WebRTC media server infrastructure; and Mitel Networks Corporation, which provides carrier-grade enterprise voice platforms with embedded WebRTC connectivity.

Question 6

Why should a buyer choose Quobis?

A buyer should choose Quobis when needing to integrate modern web and mobile communications directly into existing carrier-grade voice infrastructure without performing costly rip-and-replace overhauls. A primary scenario is corporate telephony integration for Microsoft Teams: Quobis Phone embeds corporate voice calling directly within the Teams interface while allowing enterprises to retain their existing SIP trunks, carriers, and PBXs, avoiding per-user Microsoft Phone System licensing fees. Quobis is also well suited for European public institutions and regulated enterprises subject to strict digital sovereignty mandates (such as NIS2 and the Cyber Resilience Act) that require EU-governed, non-proprietary software stacks. Furthermore, contact centers seeking to add browser-based click-to-call or video escalations directly into established routing engines (such as Talkdesk or traditional ACDs) can deploy Quobis Click to Call with contextual metadata routing.

Sources: [4] [9] [10] [11]

Question 7

Why might a buyer choose a competitor instead of Quobis?

A buyer might choose an alternative if they require a standard, off-the-shelf business phone system with automated self-service onboarding, packaged domestic calling minutes, and integrated hardware phone delivery. Organizations lacking in-house telecom engineering or SIP architecture experience may find Quobis's carrier-grade integration focus more demanding than turnkey UCaaS platforms like Zoom Phone or RingCentral. Additionally, companies seeking a widely recognized commercial mobile softphone with instant app-store deployment and turn-key push provisioning may prefer Acrobits Cloud Softphone or CounterPath Bria Enterprise. Software development teams building proprietary consumer video applications (such as social video streaming or gaming) that do not require SIP or telecom core interconnectivity may favor developer-centric media platforms like LiveSwitch or Twilio.

Question 8

What are Quobis's key strengths and limitations?

Quobis demonstrates notable strengths in technical domain expertise and architecture flexibility. As an early pioneer in WebRTC application server development, Quobis maintains proven expertise in bridging WebRTC and SIP/IMS core networks. Another key strength is its deep alignment with European sovereign telephony, offering vendor-agnostic compatibility across leading SBC vendors (Oracle, Ribbon, AudioCodes) and open-source stacks (Kamailio, Asterisk, FreeSWITCH). Conversely, a primary limitation is that Quobis is not an out-of-the-box, self-service SaaS product; deployments often require dedicated systems integration, network engineering, and clear telecom infrastructure ownership. Additionally, Quobis maintains a smaller global corporate presence compared to large multinational telecom vendors, making it more dependent on direct consultative engagements and specialized regional carrier relationships.

Question 9

What buyers should verify before purchasing from Quobis

1. Confirm network infrastructure compatibility by auditing your existing SBC, PBX, and SIP trunk certifications against Quobis WAC specifications. 2. Review Microsoft Teams integration architecture to verify whether your deployment will utilize Direct Routing SBC infrastructure or the Quobis Phone client app. 3. Validate push notification architecture and mobile OS battery-optimization compliance for custom Quobis mobile SDK implementations. 4. Determine SLA scope, 24/7 technical support tiering, and operational maintenance responsibilities between in-house engineers and Quobis. 5. Verify regulatory and data privacy boundaries regarding whether call signaling, media streams, and caller scoring data remain entirely within your private cloud or on-premises environment.

Other points to check

These notes came with the category Top 10 result. They suggest questions to raise with vendors—not verified findings about Quobis or reasons for its position.

Read the original test notes
  • The strict criteria requiring headquarters in Spain combined with carrier-grade WebRTC application server and softphone overlay platform specialization yielded only one qualified provider; other Spanish telecom providers operate primarily as retail/wholesale SIP trunk operators or PBX resellers rather than developers of carrier-grade WebRTC-SIP application server software.
Question 10

Why might AI recommend Quobis's competitors instead?

Acrobits may be recommended when a service provider requires an off-the-shelf white-label softphone with automated app publishing, turnkey push notification infrastructure, and self-service portal administration. Acrobits, a Sinch company, positions Cloud Softphone as a market-ready solution trusted by 500+ businesses worldwide. CounterPath may be recommended when an enterprise seeks an established commercial desktop and mobile UC client (Bria) with centralized provisioning, without requiring bespoke core telecom integration. PortSIP may be recommended when an organization is procuring a complete, self-contained multi-tenant PBX software suite with built-in SBC functionality and native mobile apps rather than an overlay application server. LiveSwitch may be recommended when developers require specialized high-concurrency SFU/MCU media server infrastructure for custom video streaming, gaming, or broadcast use cases.

Why this page exists: Buyers use AI to research vendors before making a shortlist. We preserve each response and its test date so you can see what appeared in that search.

How responses are checked: Selected questions about competition, differentiation, concerns, and recommendations are sent to a second model to check against available sources. Where that review produces usable findings, we show the original response and what the review found or changed. Other answers may cite sources without a separate review.

How the search is chosen: Before the Top 10 test, one model identifies the most appropriate market, buyer need, and region for this company. A second model reviews those inputs. The reviewed inputs become the search used for the blind Top 10 test. The market shown is where the test placed the company, not a category verified by TMC or chosen by the company. It may be broader, narrower, or different from how the company describes itself. That difference is part of what this page records.

What the ranking means: The Category Top 10 shows how the company appeared in this specific search. It is not a measure of quality, size, or market share. The reviewing model checks the test inputs, not the returned ranking. Linked names have live company profiles; identity verification does not independently verify every recommendation claim.

For companies: This record shows what the test picked up and which sources it cited. Missing or mistaken details may point to public information worth clarifying, but do not by themselves explain why the response said what it did.

Exact test setup and model roles

This result uses a two-model process before the ranking. Gemini proposed the most applicable provider category, buying context, and geography from its company research; Claude independently reviewed and could correct those inputs. The final Top 10 list was then generated by one blind test of Gemini, which received the reviewed category, buying context, geography, and date—but not Quobis’s identity. Claude did not review or rerank the returned Top 10 list, so the ranking itself is not a consensus across AI systems. Provider names identify the AI family; exact model versions and testing configuration are maintained internally.

The original test notes are available with the buyer checklist.
