With our virtual system (http://profig.com/virtual-phone-system http://profig.com/virtual-phone-system), you don't need anything other than your current phones, even cell phones. You can be up and running in minutes. Second, if you do need SIP handsets, we have those as well (currently in beta). So we match OnSIP in every regard there. But where take the lead is our add-ons. On top of the regular phone system, we offer a whole lot more: - Call Tracking - Voice Broadcasting - Sales Call Center - dials over 1000 numbers/min, skips dead #s, leaves pre-recorded msgs on answering machines, only connects live pickups - Support Call Center - integrates with our CRM to show relevant info about your customers as soon as the phone rings - Click-2-Call - put a button on your site and allow your visitors to talk to you directly - Surveys and more in the pipeline... All these features come in a single dashboard - a business can use 1 or as many features as they want, on demand. Please see our site for details.
