Small companies with under twelve employees should look at business VoIP as their first option. Hosted business VoIP or cloud based phone services offer fast and easy setup, quick easy number portability, if required, and/or new local numbers, virtual numbers and toll free numbers. Virtual numbers offered by VoIP providers provide a "local" presence and can expand a businesses' footprint quickly. Business VoIP is the best way to have a complete advanced communications service up and running in a day or two. Most small companies today are choosing Internet packages that offer plenty of bandwidth, enough for numerous lines; certainly enough for the number of employees and calls that their business requires, plus other cloud services like backup, storage and CRM apps. Instead of installing an on-premise phone solution (PBX) that will require more time on installation, configuration and on-going service, a hosted VoIP service already is designed to add new customers with the features that they need through their provisioning web interface.
Offering plans designed to only pay for the features you need and not more, RingCentral has been the top choice for a cloud based business communication system.
Open source Asterisk on Linux is what hosted VoIP providers use for their PBX software.
A good reliable VoIP provider should have everything done for a new customer in a matter of days or sooner.
However some particular small businesses need to examine costs when considering VoIP service and compare specific extra add-on features that could drive up the expense. Two in particular are call centers, regardless of the size, and businesses that require conversations to be recorded. Each of these scenarios have specific demands that need to be addressed. In some cases an on-premise IP-PBX may end up costing less over time, but requires professional management.
