Important: The Cisco phones use TCP only, when you add Cisco extensions, set the Transport to TCP-Only. Once it's running, register and update all the modules (if necessary). Deploy the current version and select Asterisk 13 at installation. To start, you will need a FreePBX installation, working and updated. When I started working with these devices I was unable to find a source of information that provided that, so I made one. This is not intended to be an exhaustive investigation into the workings of these devices, it does not answer every question that could be asked, or deal with every possible configuration of the systems it provides a working template from which further work can be done by the user if desired. Where files are provided, the first line in each is a commented out line in the relevant language, showing the name apportioned to that file. Everything here has been tested by building a new FreePBX server and following these instructions to end up with a working solution.

FreePBX 14 distribution (tested against 14.0.1.36)Īll of the notes here are based on my research, drawing on the works of others and many (many) hours of trial and error.

Cisco firmware 11-0-1-11 for the 8800 series.

There will be some inconsistencies until this is finished.Įverything in this document has been tested on a clean install of FreePBX and confirmed working with the following specific versions: This document is being updated to work with Asterisk 13. To get the most out of these phones, Asterisk needs a patch applied from There's an amount of work to be done to get here, and hopefully there is enough information here to help you on your way. They actually work better in some areas when driven by Asterisk. If you fall into the first category then you may be pleased to hear that they can work very well with an Asterisk system, no Cisco Unified Call Manager required.

Some people like Cisco handsets, some people don't.

You will have to get upgrades manually and apply them manually. You assume all risks herein and will no longer be able to use upgrade scripts without breaking functionality. Steps in this document end up modifying the version of Asterisk provided FreePBX.
