South African businesses are rapidly adopting online collaboration tools, yet many still juggle a separate voice‑calling system. The split stems from costly, technically‑demanding integrations that force organisations to maintain duplicate services and to settle for fragmented customer experiences.
Hybrid and remote work has amplified these pain points. While office staff rely on stable fibre connections, remote workers depend on consumer broadband that can vary wildly. This creates a patchwork of network quality—from high‑speed LTE in branch offices to less reliable fibre‑to‑the‑home links. In addition, companies must support a growing mix of endpoints: traditional desk phones, soft‑phones, mobile apps, and browser‑based clients that receive continuous updates. Users range from knowledge workers needing full UC&C features to transactional staff who only require basic calling.
Call2Teams from Telviva promises to collapse this complexity by embedding voice directly into Microsoft Teams. The service bridges any Teams Phone, PBX, or SIP trunk to the Teams environment, eliminating the need for extra hardware or specialised software. It operates as a true multi‑tenant cloud platform, billed per user, and lives natively inside the Microsoft ecosystem.
Call2Teams: A Unified Voice Solution for Microsoft Teams
Adopting a single communication ecosystem yields tangible business advantages. When every employee works inside the same hub, managers gain real‑time visibility of presence, making it easier to decide when to call, message, or invite someone to a meeting. Integrated analytics also reveal interaction patterns, enabling teams to streamline workflows and dissolve the traditional “front‑office‑back‑office” divide.
Despite the ubiquity of Microsoft 365, research from BMI‑TechKnowledge shows that fewer than 5 % of South African Teams users have native voice enabled. Consequently, most organisations continue to operate a stand‑alone PBX, paying extra fees and managing separate support channels. Historically, adding voice to Teams required a specific Phone System licence and a Direct Routing partner—processes that were both time‑consuming and expensive.
Telviva’s Call2Teams tackles these hurdles with several key benefits:
- Speed and cost: Deployment shrinks from weeks to days, while savings can reach up to 25 % compared with traditional Direct Routing.
- Easy migration: Existing numbers, including DDIs, port seamlessly without service disruption.
- Zero complexity: Telviva shoulders all technical layers, so businesses avoid managing Session Border Controllers or becoming telephony experts.
- Single point of accountability: One contact handles issues, removing the blame game among Microsoft, the telecom provider, and SBC vendors.
- Advanced features: Teams users unlock Class 5 PBX capabilities such as call transfers, conferencing, and sophisticated call handling.
- Governance: Integrated call‑recording meets regulatory standards, offering auditable and retrievable logs directly from Teams.
- Seamless experience: Employees stay within the familiar Teams interface—no extra desk phones, apps, or plugins are required.
- Unified workforce: Voice‑enabled and voice‑only Teams users communicate as if on a single system, erasing silos.
Local support is another critical factor. Telviva has mapped its platform to South African regulatory requirements—including Icasa, POPIA, and number‑portability rules—ensuring compliance when organisations migrate to the cloud.
The shift to a unified voice‑plus‑collaboration stack also yields productivity insights previously hidden in separate systems. By monitoring call volumes, response times, and meeting participation within Teams, businesses can fine‑tune staffing models and improve customer service metrics. Moreover, the centralized approach reduces administrative overhead, freeing IT teams to focus on strategic initiatives rather than juggling multiple vendor portals.
For companies still hesitant about native Teams voice, the promise of a waived setup fee and a streamlined onboarding process lowers the barrier to entry. The cloud‑based model also future‑proofs the organization, allowing easy scaling as remote work patterns evolve.
In an environment where hybrid workforces demand consistent support across diverse devices and network conditions, integrating voice into Microsoft Teams via Telviva’s Call2Teams delivers a single, cohesive communication platform. By eliminating fragmented systems, reducing costs, and providing deep operational visibility, South African enterprises can finally move from disjointed tools to a fluid, unified collaboration experience.
