What VoIP Costs
Hosted VoIP is usually billed per user per month and includes features that once required an expensive on-site system. Phones can be purchased or leased, and softphone apps reduce hardware costs further. Most small businesses spend less than they did on traditional phone lines while gaining features.
Moving Your Existing Numbers
You can keep your current business numbers. The provider ports them over, usually within a few weeks, and the switch is scheduled so callers never notice. Plan the cutover for a quiet time and test call routing before the old lines are disconnected.
