This company earned a high spot on our best virtual phone system provider list because it streamlines internal communication and entirely eliminates your phone bill with its cloud PBX. You can use the softphone desktop application to conduct conference calls with remote team members with or without video.
However, while understanding the basics of VoIP and SIP is important, setting one of these systems up will require some general network skills, too. For the best voice quality, your network will need to meet certain minimums levels of throughput for upstream and downstream data. In addition, you'll also need to meet a minimum latency number (that is, the time between when a signal leaves a remote computer and when your system receives it), typically measured in milliseconds. You'll also need a business-grade connection to the Internet if that's where your call traffic is going to go.
