Top 3 VoIP appliance Picks for 2021

Best on-premise VoIP PBX systems for total control.

The advantages to an in-house phone system are control, cost savings over time, lower costs to expand, and the ability to choose SIP trunk providers for lower cost calls. Cloud based phone service (hosted VoIP) is great for many small businesses and other unique situations, but for mid-sized and larger companies that want to have complete control and have the resources to manage a VoIP system, like call center operations, hospitality services, or companies that experience heavy call volumes and need a greater number of lines (trunks), then an on premise IP-PBX phone system is most likely the best choice.
Most hosted VoIP providers offer some extended features such as conferencing, call recording, and call analytics, to name a few, that may come with additional fees driving up monthly costs. An on-premise phone system lowers costs in these situations.
