What is a Premise (On-Site) Phone System?
Premise phone systems can be described as unified communications solutions that function as a private telephone network hosted on-site. In this scenario, the on-premise phone system will use a variety of communication channels like analog, ISDN, and Voice over IP phone systems to make calls both internally and externally.
With robust telephone systems hosted on-site, you can have more phones than physical lines. This enables calls between internal users at no extra cost. Premise telephone systems also come with all the industry standard features like auto attendants, conferencing, music on hold, unified messaging, and more.
