The site has supported IP Office systems since Release 1.0.

However, we normally only provide full information for the releases that are still sold and supported by Avaya. Typically, that means the last two major releases.

•User Guides Section
This section  only includes information for the IP Office releases still supported by Avaya.

•Technical Manuals Section
This section includes information for all IP Office releases. However, for releases no longer supported by Avaya, we only retain the PDF format English documentation and no longer update their content.
