Yesterday I upgraded a Voice Over IP (VoIP) PBX to the 3CX Version 16 software. I had to do a new install of the software, since the password to the old software was lost and it had to be wiped out and new software installed. Luckily I didn’t have to make any firewall changes since the Sonicwall firewall was already set up to allow VoIP traffic in and out from the Internet over a SIP trunk from a company named Fusion.
So how does a VoIP PBX work? WONDERFULLY in this case.
In the case of this 3CX PBX, it has some very advanced features designed for small and medium-sized businesses. It not only works with most VoIP phone handsets, it can route calls over the internet to cell phones, it can allow a user to make a call from their cell phone but it looks like it is coming from their office phone, it can capture voice mail and forward it via email to the recipient, it can receive inbound calls and ring both the desk phone and cell phone simultaneously. These are just a few of the features available. And the software is very, very inexpensive. In fact, for most businesses using traditional phone lines from AT&T or Cox, installing a VoIP PBX like 3CX can save hundreds or even thousands on the monthly phone bill while providing much more functionality. In nearly all cases a VoIP PBX will pay for itself in phone charges in less than a year.
Run PBX locally or in the Cloud
Now with 3CX
VoIP phone sets can be purchased for around $100 or so, depending on features. And of course, you will need an internal network to run the VoIP system on. This can be done with switches and routers or even a WIFI network.
