A robust telecom setup is built on several foundations. Start by assessing the quality of connectivity available at your sites—fibre, copper, 4G/5G—based on location and expected usage. You also need to factor in your capacity to handle traffic peaks, network redundancy to prevent outages, and strong data security. Finally, ensure the solution is scalable enough to evolve with your business needs and digital transformation.
-
Start with an analysis of your daily operations: data volume, calls, video conferencing, and access to cloud services. Then, evaluate the number of simultaneous users, business-critical applications in use, and the geographic distribution of your teams. This helps determine the required bandwidth, the most suitable technology (fibre, SDSL, VPN/MPLS…), and any security layers needed to ensure performance.
-
Traditional phone lines use the public switched telephone network (PSTN), while IP telephony relies on the internet to transmit calls. VoIP allows businesses to centralize communications into a single, flexible platform. It often includes advanced features like unified messaging, remote call handling, and integration with collaboration tools. Unlike fixed lines, VoIP systems are easier to scale and better suited to today’s mobile and hybrid work environments.
-
A telecom system handles sensitive data—voice, files, access credentials—so securing every layer is essential. This includes encrypting communications, managing access rights, segmenting networks, and implementing real-time monitoring. Physical infrastructure security and compliance with local regulations (like GDPR) are also key. By anticipating these risks, companies can reduce exposure to cyber threats and data breaches.

Successful migration requires detailed planning and structured technical support. Start by identifying critical services, mapping out the switchover process, and ensuring number portability. Conducting a pre-migration audit helps prevent unforeseen issues. It’s also important to include testing and user training phases to ensure smooth adoption. With the right preparation, continuity of operations is fully maintained throughout the transition.
