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.
