What is an IP PBX?
Internet Protocol Private Branch Exchange, or IP PBX, is a system that switches local phone lines to voice over Internet protocol, or VoIP. In other words, your phone calls are routed over the Internet or your local network (LAN) with an IP PBX system. The services of an IP PBX are generally the same as other internet-based PBX services. The utilization of the Internet for business phone calls still allows for multiple phone lines to be connected through one phone number for businesses large and small.
How Do IP PBX Systems Work?
Users of these phone systems plug their IP phone into the nearest LAN port. The IP phone then registers automatically to the VoIP phone system, making it exceptionally easy for anyone to install. The IP phone keeps its number and functions as normal, regardless of where it is plugged in—whether at your office desk or in a hotel across the world. This flexibility is made possible because of SIP protocol. SIP, or the session initiation protocol, is a way of signaling and controlling multimedia communication sessions.
An IP PBX system manages several SIP phones or VoIP phones, controlling the entire phone system network. When a phone requests to make a call through the system, the IP PBX establishes the connection to the Internet. The PBX connects an internal call within the network directory or routes an external call through a VoIP gateway or a VoIP service provider to the outgoing destination.
What Are the Benefits of IP PBX Systems?
There are a multitude of benefits of switching to an IP PBX system. There are, however, three major benefits to note:
- With a single line for each user, an IP PBX engages data and voice networks. This way, Internet access, VoIP communications and traditional telephone communications are compatible and synced. So as your business grows, the IP PBX easily keeps up with you.
- IP PBX systems save you money with upkeep and maintenance costs, as it is software-based. The IP PBX is owned by the business, just like a traditional PBX. Because an IP PBX routes phone calls through the Internet, you no longer have to use the telephone network for making calls, which also reduces costs.
- IP PBX phones systems remain scalable. While older PBX systems would be limited to a physical number of phone ports, IP PBX systems are not; therefore, you don’t need to replace your phone system when your company grows!
