Why choose cellular over VoIP for your elevator phone line?

Both cellular service and VoIP (Voice over Internet Protocol) have their own advantages and limitations, and which one is better depends on various factors, such as the specific needs and requirements of the user.

Traditional elevator emergency systems relied on copper telephone service for their connection. With copper services being retired, updating your elevator phone line is important.


Cellular service provides reliable voice and data communication over a cellular network, which offers good coverage in most areas. Cellular service may be more reliable for emergency situations, as it is not dependent on a Wi-Fi or wired network, making it a great candidate for elevator phone service.


VoIP is a technology that allows voice communication over the internet, making it a little more cost-effective than cellular service. It can offer more features, such as video calling, call forwarding, and voicemail transcription. However, VoIP quality is impacted by network congestion and dropped or even weak internet connections, making VoIP less reliable in emergencies where the internet connection may be disrupted.

Generally, whether cellular service or VoIP is better depends on the specific needs and circumstances of the user. Cellular service is better for those who need reliability and coverage, while VoIP may be better for those who need more features.
