How To – Using telephones on the CVADN

Information on configuring VoIP telephones is coming soon… The goal is to have a cache of phones for deployment to an incident sites for responders to use, allowing them to communicate any time using a familiar tool and freeing AUXCOMM personnel for other tasks. If you are considering buying a phone, we have tested the Yealink T33G desk phone and the Yealink W60B/W56H cordless base/handset. Both work very well, run/charge on 5 VDC, come with warranties, and are not much more expensive than equivalent discontinued Cisco and Polycom phones on eBay. The cordless phone would be great for a go-box; the desk phone would be a great shared resource. Softphones on laptops will also be useful.

Download the Jitsi Desktop softphone from and install it.

The first time you run Jitsi, you’ll be presented with a window to make a new account. Cancel out of that window; it doesn’t allow setting some essential options. You’ll see:

Choose “Add new account…” from the “File” menu. On the “Add new account” window, click “Advanced”.

New account

Fill in your SIP id and Password using the credentials you received previously. Then select the “Connection” tab.

Click “Sign in” and you should connect to the CVADN telephone switch (the private branch exchange, or PBX). Your status (next to the generic picture) should show “Online”.


To make a call, type the extension number into the “Enter name or number” space and click the green telephone icon.
