10 Reasons To Switch To An IP PBX
Note: TelephonyWorld.com has a write-up about different reasons to move to a IP based PBX Platform.
"
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.
"
Enterprises don’t need to disrupt their current external communication infrastructure: An IP PBX is able to connect to traditional PSTN lines via a VoIP gateway - so an enterprise can keep its regular telephone numbers.
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.
