PBX Development

Introduction to PBX technology

Learn the basics

A PBX (Private Branch Exchange) is responsible for the communication line establishment between communication end points. For this purpose SIP accounts and authentication are used. The end points attached to the certain SIP accounts are called extensions of the PBX. These extensions can be physical VoIP telephone devices, PSTN adapters, software telephone solutions or so-called virtual extensions.
Ozeki VoIP SIP SDK dramatically accelerates PBX development: Check How to develop SIP PBX effectively with Ozeki SIP SDK.

What you need

  • Powerful server configuration
    The PBX system can work effectively if you have a really powerful startup configuration on it. You can set up rules for the number or order of the phones that will ring when a number is called, or define special features for some communication purposes like voice mail, etc.
  • PSTN connection
    You can also make connection towards the traditional wired and mobile communication network (PSTN) by using a simple adapter that is connected to the PBX. In this case you will be able to call any PSTN numbers from a VoIP phone and vice versa.
  • LAN
    You can create an effective company communication network by installing a PBX system on your local area network. This will make your workers' communication easier and free.

Virtual extensions

The virtual PBX extensions are built-in PBX modules that are not traditional communication end points but serve some special purposes, for example, voice mail, answering machine functionality or IVR server functionality.

Capacity and performance

  • Number of extensions - capacity issues
  • Codec translation - when the softphones do not have the same codecs
  • Peer to peer data transmission - better performance

Extending PBX functionality

  • Call assistant - for making your work easy with useful and helpful functionalities
  • Connecting multiple PBXs - for connecting separate office departments in one communication network
  • Call tunneling - for call encryption
