IP PBX System Connectivity
LAN based
IP PABX solution
• 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 gateways - 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 phone lines.
How IP PABX works?
An IP PBX or IP Telephone System consists of one or more SIP phones (software based or hardware based), analog phones connected by adaptors, 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 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.
Benefits of IP PABX
o Cost reduction
o Easier to manage
o Eliminate phone wiring
o Eliminate vendor lock-in
o Scalable oTwice the features
IP PABX Standard Features
• Standard phone features (call waiting, transfer, call pick-up, DND, call forwarding) • Auto attendant - a voice menu system that allows callers to be transferred to an extension without going through a telephone operator or receptionist. The auto-attendant is also known as a digital receptionist.
• Voicemail and voicemail to email - A voice mail system is a centralized system used in businesses for sending, storing and retrieving audio messages, just like an answering machine would do at home. Each extension in a phone system is normally linked to a voice mailbox, so when the number is called and the line is not answered or is busy, the caller listens to a message previously recorded by the user. This message can give instructions to the caller to leave a voice message or gives other available options, such as paging the user or being transferred to another extension or a receptionist. The system can also send the voicemail file to an email specified by the user.
• Call parking - Another handy feature is called call parking. Call parking allows you to place a call on hold in a “parking lot,” so that it can be taken off hold from another extension.
• Follow me – a feature that tries to call all known numbers of a certain user (ex. If the IP phone is not picked up after several rings, the system will try to connect to the cell phone)
