Frequently asked questions
VoIP technology continues to advance, but it's unlikely to completely replace cellular networks due to the latter's wider coverage and reliability, especially in emergencies. Both technologies also serve different purposes and are likely to coexist in the foreseeable future.
Both VoIP and cellular communication face security challenges. VoIP calls are vulnerable to internet-based attacks, while cellular networks can be intercepted. Both technologies use encryption, but neither is entirely foolproof, making their security levels comparable.
Disadvantages of VoIP include dependency on internet connectivity, which can be unreliable in certain areas, leading to call quality issues. VoIP is also susceptible to power outages unless backup systems are in place. Emergency services might face challenges in accurately locating VoIP callers during crises.
Unlike cell phones, which rely on cell towers to make calls, VoIP digitizes audio and transmits it over the internet. This means you can make a VoIP call on any internet connected device, including cell phones, laptops, tablets, and more.
