VoIP and Business Phone Systems
Quick answer

VoIP sends calls over the internet or your network instead of old phone lines. An IP PBX or cloud phone system gives each person an extension, routes incoming calls to the right desk or group, supports voicemail and mobile apps, and lets branches share one system. It needs reliable internet and power backup to be dependable.
