HVoIPM is a small desktop application that can be used to monitor one or more heterogenous VoIP or PBX systems. Users can choose from a range of device monitors (or build their own) to provide telephony data to be logged or displayed on screen. For instance, the software could be used to log all calls made by a certain device, or to flash up a warning or launch a process when a VoIP device's registration state goes offline.

That depends what's happening with your device. Sometimes it might look like these screenshots.

If you have a Linksys PAP2 device, all you will need to do to get HVoIPM working is edit the configuration file ("Hardware VoIP Monitor.exe.config"), changing the LinksysPAP2DeviceMonitor:Hostname value to that of your device's URL, including the http:// prefix.
If it doesn't work, read the configuration file. If that doesn't help, refer to our forum threads (1, 2) or let us know. When reporting problems, include a copy of your "system.xml" log file with any report.
Alternately, if HVoIPM doesn't quite do what you want, have a look at the Sipura 3000 System Tray Monitor.
Support for further devices is provided by writing simple device monitor plugins. These are simple to write, and we'd love to receive any contributions. Below is a snippet of an explanatory message, along with some example source code showing how it can be done. Drop us a note if you need any advice or need support for a particular device.
Hi, and thanks for your kind words.
It should be possible to get HVoIPM working against your Sipura SPA-2000. As you've asked for the source code, I'll explain roughly how. Basically, there are two ways to figure out what a VoIP device is doing: the first is to packet sniff and examine the RTP/VoIP traffic that's going back and forth, and the second is to introspect the device itself, over whichever interfaces it exposes.
The first technique is almost foolproof -- it'll work with any VoIP-compliant device to return a fairly limited set of base information. The problem it that in order for this to work, the machine that you're running the sniffing software on either needs to have it's network adapter running in promiscuous mode, or be sitting on a monitor port on your switch. (Because if you have a switch rather than a hub, like most people, your SPA-2000 won't route traffic to your computer.) There are a few tools that take this approach. Vomit, for instance.
This won't really work very well for a lot of small-end consumer VoIP devices of the sort that HVoIPM works with, otherwise I'd port some of the GPLed Linux C to .NET. (It'd work well with Softphones and Skype clones, though.)
HVoIPM uses the second approach. That is to say, it tries to get whatever data it can from the devices by looking at the interfaces they have. Unfortunately, most of the first generation consumer VoIP boxes we're seeing now are shit. Some of them offer absolutely no decent access at all. Whilst most professional equipment provides a TAPI interface, most cheapo new stuff only provide little web interfaces. The Linksys PAP2 is one of the best in this regard, and when configured to work with one of these devices, HVoIPM basically just screen-scrapes the HTML from the PAP2 device. The SPA-3000 provides a great interface for this, too, and I wouldn't be surprised if the SPA-2000 and SPA-2002s did as well.
If your SPA-2000 doesn't have a decent enough web interface (or other interface), possibly it could be flashed with the PAP2 firmware. (If it really is the same device inside.). Alternately, HVoIPM could pull data out of its telnet interface, if it has one, or from any SNMP flags it has.
HVoIPM isn't Open Source or GPLed (it may be later...), though I'm happy to send you the C# source code for some of the device monitors. If you load up Visual Studio, and create a new project with these files you should be able to build your own device monitor classes, which can then be specified in the HVoIPM configuration. It's possible for HVoIPM to report on additional properties as well as the basic ones that it does now, too. It should be easy enough to adapt the code to work with an SPA-2000. If you do, please send it to me. :-) If you don't, well... send me a dump of the SPA-2000's HTML and I'll write it myself. I've attached a dump of the PAP2's HTML so you get the idea.
I think I've included most of the relevant source files here -- you'll probably need to comment out a few references to get it all to build, but you should get the picture if you're familiar with C#. Excuse the poor code -- I know that the LinksysPAP2DeviceMonitor class is extremely suboptimal in many ways, especially with all of the String creation & disposal it does.
