The benefits of replacing your old PBX with an IP PBX
What is an IP PBX?
An IP PBX is a complete telephony system that provides telephone calls over IP data networks. All conversations are sent as data packets over the network.
The technology includes advanced communication features but also provides a significant dose of worry-free scalability and robustness that all enterprises seek. The IP PBX is also able to connect to traditional PSTN lines via an optional gateway - so upgrading day-to-day business communication to this most advanced voice and data network is a breeze!
Enterprises don’t need to disrupt their current external communication infrastructure and operations. With IP PBX deployed, an enterprise can even keep its regular telephone numbers. This way, the IP PBX switches local calls over the data network inside the enterprise and allows all users to share the same external lines.
How it works
An IP PBX system consists of one or more SIP phones, an IP PBX server and optionally a VOIP Gateway to connect to existing PSTN lines. The IP PBX server functions in a similar manner to a proxy server: SIP clients, being either soft phones or hardware-based phones, register with the IP PBX server, and when they wish to make a call they ask the IP PBX to establish the connection. The IP PBX has a directory of all phones/users and their corresponding SIP address and thus is able to connect an internal call or route an external call via either a VOIP gateway or a VOIP service provider. More information and commonly asked questioned about IP PBXs can be found on IP PBX, SIP & VOIP FAQ - http://www.3cx.com/PBX/IP-PBX-faq.html
The top 10 Benefits
Benefit #1: Much easier to install & configure than a proprietary system:
An IP PBX runs as software on a computer and can leverage the advanced processing power of the computer and user interface as well as Windows’ features. Anyone proficient in networking and computers can install and maintain an IP PBX. By contrast a proprietary system often requires an installer trained on that particular proprietary system!
Benefit #2: Easier to manage because of web/GUI based configuration interface:
An IP PBX can be managed via a web-based configuration interface or a GUI, allowing you to easily maintain and fine tune your system. Proprietary systems have difficult-to-use interfaces which are often designed to be used only by the technicians.
Benefit #3: Significant cost savings using VOIP providers:
With an IP PBX you can easily use a VOIP service provider for long distance and international calls. The monthly savings are significant. If you have branch offices, you can easily connect systems between branches and make free calls.
Benefit #4 Eliminate wiring!
An IP PBX allows you to connect hardware phones directly to a standard computer network port (which it can share with the adjacent computer). Software phones can be installed directly onto the PC. You can now eliminate the wiring and make adding or moving of extensions much easier. In new offices you can completely eliminate the extra ports to be used by the phone!
Benefit #5: Eliminate vendor lock in!
IP PBXs are based on the open SIP standard. You can now mix and match any SIP hardware or software with any SIP-based IP PBX, PSTN Gateway or VOIP provider. In contrast,
