Application Notes

This area contains pages dedicated to Application notes.

These application notes are documents that are being version controlled and are kept to a particular format, to make it easier to read.

All Tutorials that were previously on this Website are being converted to Applicaiton Notes and are being revised, updated and re-tested against the latest version of Elastix.

You will note on the front page of every Application note written in this way, will be an easy to read summary, regarding the Elastix system it was tested on, when the document was written, whether it is backward compatible, and the level of expertise needed to accomplish the implementation.

These application notes are written up and tested in a lab that has been specially setup to write these notes. This includes:

· 5 x Elastix IP PBX Hardware with a mixture of SIP only, Digium, Sangoma, OpenVox Cards
· 1 x WAN Simulator (including latency, jitter, random disconnects, random packet drop)
· 8 x Consumer / Business routers, including Drayteks, Cisco 1842, Cisco 877, Linksys WRT54GL
· 2 x IBM XSeries servers running VMware with 8 images of various versions of Elastix IP PBX
· 1 x Standard Microsoft SBS Network providing DHCP and DNS and Mail system
· 2 x Linux Servers

The Elastix IP PBX systems, both hardware and Virtual based have image systems to refresh the systems to limit infection from other testing. Combined with a range of Phones, which include Aastra, Linksys, Cisco, Yealink, it provides a reasonable cross section of typical systems currently in the field.

These application notes are not just done in isolation either. Behind them is over 6-7 years of commercial implementation of IP PBX systems, utilising these methods and concepts. The Lab is just used to reconfirm the implementation in a less production like environment.
