Overview of this book

Open source telephony systems are making big waves in the communications industry. Moving your organization from a lab environment to production system can seem like a daunting and inherently risky proposition. Building Enterprise Ready Telephony Systems with sipXecs delivers proven techniques for deploying reliable and robust communications systems. Building Enterprise Ready Telephony Systems with sipXecs provides a guiding hand in planning, building and migrating a corporate communications system to the open source sipXecs SIP PBX platform. Following this step-by-step guide makes normally complex tasks, such as migrating your existing communication system to VOIP and deploying phones, easy. Imagine how good you'll feel when you have a complete, enterprise ready telephony system at work in your business. Planning a communications system for any size of network can seem an overwhelmingly complicated task. Deploying a robust and reliable communications system may seem even harder. This book will start by helping you understand the nuts and bolts of a Voice over IP Telephony system. The base knowledge gained is then built upon with system design and product selection. Soon you will be able to implement, utilize and maintain a communications system with sipXecs. Many screen-shots and diagrams help to illustrate and make simple what can otherwise be a complex undertaking. It's easy to build an enterprise ready telephony system when you follow this helpful, straightforward guide.

External monitoring of system availability


There are several system services that are critical to sipXecs operating properly. These services should be monitored from an external monitoring solution that can provide up/down notifications and paging for support staff. There are several solutions available on the market to support this type of service, Zenoss (open source) and What's Up Gold being two of the more popular.

Services running on PBX server:

  • sipxsupervisor

  • sipxrls

  • sipxpresence

  • sipxpark

  • sipxconfig-agen

  • sipstatus

  • sipregistrar

  • sipXvxml

  • sipXproxy

  • ruby

  • sipxacd *— only if ACD is enabled on server

  • freeswitch *— only if conferencing is enabled on server

The following services may be provided by other network servers or by the PBX but are critical to proper operation of the system and should thus be monitored:

  • NTP

  • DNS

  • NTP

  • DHCP
