Telephony continues to be an essential part of any business. Customers call for information, suppliers get in touch for orders, employees need to remain reachable, and missed calls can directly lead to missed opportunities. Yet, many SMEs in Belgium still work with an outdated telephone exchange, limited call forwarding, or separate mobile numbers without professional oversight. VoIP telephony offers a modern solution for this.
With VoIP, or Voice over IP, phone calls are made over the internet instead of via a classic analogue or ISDN line. This makes business telephony more flexible, scalable, and better integrated with the digital workplace. GVISION assists SMEs in Brussels, Asse, Zellik, and throughout Belgium with professional VoIP solutions based on Yeastar. The Yeastar P-Series combines classic telephony features with unified communications, mobile apps, call centre functions, Microsoft Teams integration, and new AI capabilities such as AI Receptionist, call transcription, and automatic summaries.
VoIP (Voice over Internet Protocol) telefonie is een manier om te bellen via internet in plaats van via de traditionele telefoonlijnen. Met VoIP worden je telefoongesprekken omgezet in digitale data en via het internet verzonden, net als e-mail of webpagina's.
VoIP stands for Voice over Internet Protocol. In simple terms, this means your phone calls are made using your internet connection. You still use professional phone numbers, desk phones, headsets, or mobile apps, but the underlying technology is more modern and flexible than traditional telephony.
For a small to medium-sized enterprise (SME), VoIP telephony means that telephony is no longer tied to one physical location. Employees can make calls via a desk phone, computer, smartphone, or web client. An employee working from home can remain reachable on the company's main number. A technician on the road can make calls via the mobile app. VoIP also enables functions that were expensive or complex with classic telephony: auto-attendants, queues, opening hours, voicemail-to-email, call recording, reporting, and integration with CRM or Microsoft Teams.
Why traditional telephony is no longer sufficient
Many companies continue to work with the same telephone exchange for years. As long as calling works, there seems to be no problem. But in practice, more and more limitations arise. A classic telephone exchange is often difficult to adapt: adding new users requires technical interventions, call forwarding is limited, home workers find it difficult to call the landline number and reporting is lacking. When the exchange breaks down, repairs become expensive or even impossible.
Furthermore, the way of working has changed. Employees are no longer always in the office, customers expect quick responses, and companies are using Microsoft 365, Teams, CRM systems, and mobile devices. VoIP telephony fits better with this reality. This is particularly important for SMEs in Belgium because availability directly impacts customer service: a missed call can be a missed sale.
Yeastar as a professional VoIP solution for SMEs
GVISION works with Yeastar because the platform is suitable for SMEs that want professional telephony without unnecessary complexity. Yeastar offers a modern PBX solution with features for calling, collaboration, customer communication, and integrations. A PBX is the company's telephone system; the Yeastar P-Series supports flexible deployments (on-premises, cloud, or software) and works with SIP trunks and IP phones of your choice.
Key Yeastar features for SMEs include professional auto-attendants, incoming call queues, business hours and holiday schedules, mobile phone forwarding, voicemail to email, call recording, reporting and call logs, a mobile app and desktop client, integration with Microsoft Teams, CRM integrations, and AI features. For businesses currently using separate mobile phones or outdated PBXs, Yeastar provides more structure, better accessibility, and a more professional impression for customers.
Linkus: call from computer, smartphone and browser
One of Yeastar's strengths is Linkus, their unified communications client which is available for web, desktop and mobile. According to Yeastar, Linkus provides features such as calling, messaging, conferences, contact management and presence, enabling employees to stay connected across different devices.
For an SME, this means employees don't always need a physical telephone. They can make calls via their computer with a headset, via the mobile app, or via a web browser. This is useful for remote working, sales staff, technicians, and employees who are often on the go. Employees keep their professional internal extension number and the customer notices no difference. GVISION helps with the installation and configuration of Linkus on computers, smartphones, and browsers.
Professional call flows: IVR, queues and opening hours
A good VoIP solution starts with a clear call structure. An IVR, or Interactive Voice Response, is a menu system, for example, “Press 1 for sales, press 2 for support”. This gives a professional impression and helps to route calls correctly. Queues are useful when multiple employees answer calls: instead of one phone ringing endlessly, calls are distributed among available employees.
Opening hours and holiday schedules ensure that calls are handled differently outside of working hours. With Yeastar, these call flows can be professionally designed. GVISION first analyses how your company currently receives calls and then designs a clear call flow: what numbers exist, which departments should be reachable, what happens outside of opening hours, and what message the customer hears?
AI Receptionist: a smart virtual receptionist
One of the most interesting evolutions within modern VoIP telephony is the advent of AI features. Yeastar offers AI Receptionist, a virtual receptionist that can automatically answer calls, greet callers, answer questions based on its own knowledge base, and intelligently route calls to the correct destination.
Rather than a classic choice menu, an AI Receptionist can communicate more naturally: the caller can explain in plain language why they are calling. Yeastar indicates that the AI Receptionist can be trained based on a customised knowledge base and that configuration can be done without complex code, for example, with uploaded documents or a website URL. Consider a medical practice answering general questions, a real estate agency qualifying calls, or a small to medium-sized enterprise using the AI Receptionist outside of opening hours. AI doesn't always replace the human receptionist but can handle repetitive calls and improve accessibility.
AI Transcription and Automatic Summaries
In addition to AI Receptionist, Yeastar also offers AI features for call transcription and summarisation. Yeastar describes AI Call Transcription as a feature that converts spoken words in a voice or video call into written text, with time-stamping and speaker identification. Instead of constantly taking notes during the call, the employee can refer to the transcript afterwards.
Yeastar also mentions AI Call Summary, where the system can generate a summary, key points, and to-dos after a call. For an SME, this offers concrete advantages: less time wasted on manual notes, better follow-up of customer appointments, clearer internal handover, and improved documentation of support calls. AI voicemail transcription can also automatically convert voicemail messages into readable text, allowing users to view and follow up on messages more quickly.
AI Text-to-Speech for professional messages
Another AI function within Yeastar is AI Text-to-Speech. This allows text to be automatically converted into natural-sounding audio files that can be used as greetings, announcements, or spoken prompts. This is useful for businesses because professional phone messages are often forgotten or remain unchanged for years.
With Text-to-Speech, you can quickly create neat, consistent, and understandable messages: a welcome message during opening hours, an out-of-hours message, a holiday message, or menu options for departments. For many customers, the phone call is one of the first points of contact, and a clear and polished message immediately makes a better impression.
Yeastar and Microsoft Teams
Many companies use today Microsoft Teams for chat, meetings, and collaboration. That's why it's interesting when telephony and Teams can work well together. According to Yeastar documentation, Teams users can be linked to Yeastar SIP extensions, allowing the Teams app to function as a softphone and enabling users to retain existing numbers and SIP devices while continuing to use PBX features such as IVRs, queues, and call routing.
For SMEs that already deal with on a daily basis Microsoft 365 Working, this is a significant advantage. Employees can centralise their communications in one trusted environment. GVISION helps analyse whether Teams integration is suitable for your company and how to configure it correctly.
Call centre functions for SMEs
Call centre functionalities aren't just for large contact centres. Smaller businesses can also benefit greatly from features such as queuing, reporting, call recordings, and real-time insights. Yeastar P-Series includes features like auto-call distribution, queues, wallboard, agent coaching, call recording, queue callbacks, and reporting.
For an SME with a reception, customer service or technical support department, these functions are very useful. You can better track how many calls come in, how many calls are missed, and what the waiting times are. With VoIP data, what was previously gut feeling becomes measurable, allowing a business manager to make better decisions.
VoIP and cybersecurity
VoIP telephony must also be set up securely. A poorly secured telephone exchange can be misused for fraudulent calls, unwanted access or data leaks. Therefore, cybersecurity An important component of any VoIP implementation.
GVISION takes security into account from the outset for VoIP projects: strong passwords, correct firewall rules, restricting external access, secure SIP configuration, updates, monitoring, and rights management. User management is also important: when an employee leaves the company, their telephony account must be adjusted. Just like with MFA In Microsoft 365, telephony is not separate from the rest of the IT environment — it is part of the digital infrastructure.
Migration to VoIP: how is the project progressing?
A move to VoIP needs to be well-prepared. A correct migration begins with an inventory of the current situation. GVISION examines, among other things, which telephone numbers the company uses, which numbers need to be kept, how many users and devices there are, which departments need to be reachable, whether queues or auto-attendants are required, whether integration with Teams or CRM is necessary, and if the network is ready for VoIP.
Afterwards, we design the new telephone system: call flows, users, devices, opening hours, voicemail rules and diversions. We then test the solution before the final transition. A good migration ensures that the company remains reachable; number porting, device configuration, training and support are coordinated. IT audit To start, it helps to check if your network and internet connection are ready for VoIP telephony.
