Thumbs up Public Version of UNIStim Decoder for Wireshark

Question: "Can I get a copy of a plug-in decoder for Wireshark (ethereal) that will decode UNIStim messages sent to my IP Phone"

OLD Answer: "No, UNIStim is Nortel proprietary, and they do not release a decoder to the public for that"

NEW Answer: "You can't download it from nortel.com, but there IS A PUBLIC VERSION that is available if you ask for it!"


What? Yes, it's true. After a lot of hard work by many, and a lot of discussion, Nortel has produced a public version of the plug-in for Wireshark. This plug-in will not decode the entire UNIStim message set, but will provide quite a bit of information and should be all you need to troubleshoot network connectivity and registration issues. Now, don't just thank me for this, although, I did push to get this done for our customers, there is another person on the board here that had a major role in making this a reality and it absolutely would not have happened without his help and support. I'm sure you know who that is!

The decoder is NOT officially supported by Nortel support, and there is no commitment that future versions will be made available or compatible with future versions of Wireshark (formally ethereal). It is provided on an AS IS BASIS ONLY. I cannot stress this enough! We have tested it with the current version of Wireshark, and it runs just fine, but do not contact Nortel for installation or decoding support. They will not be able to assist you.

That being said, if you would like a copy I have attached it to this post for Rick to archive here. See the Wireshark documentation (Wireshark: The World's Most Popular Network Protocol Analyzer) for detailed instructions on how to install this on your PC, as well as how to setup and capture ethernet traces.

Unistim Plugin

Is this the unistim plugin that recently got added to the wireshark svn tree? I'm one of the developers on that plugin, and i just added some features. If you want i can provide an updated dll or source.

No, this one was developed by Nortel. I know others may have reversed engineered plug-ins for UNIStim though.

Nortel's plugin

Nortel claims to have one, but nobody there will come off it. I've tried to get ppl at GNTS and GNPS to man up but nobody will. We had to engineer our own. It just got added to the wireshark svn tree and i imagine will be in the next release. It decodes all unistim command types per their documentation. However the CS2k has some undocumented Unistim features that we're still working on. One of which is the CICM on the cs2k's ability to have shared unistim sessions as in m6350. anyway, I just added unistim call detection and graphing, and its currently being reviewed for checkin.

For some reason that one doesn't work for me. The other one does though.

I downloaded SVN 22800 with the unistim plugin and thus far I have to agree that it seems to provide a lot more info than the Nortel plugin.
