On-premise PBX is also known as an IP-PBX phone system. It is similar to a traditional PBX system that resides at a location, such as a computer equipment room or phone closet. The main difference is that IP routing is done with more current technology. The signaling is done with an IP phone to the IP-PBX server using a LAN. Calls can go through a traditional phone company as well as voice over Internet (VoIP) using SIP trunking.
The provider can be the one that already provides service, though a SIP trunk can be configured for use with an Internet service telephone provider (ISTP).
