There're were a few requests for a UNISTIM dissector for Ethereal, but 
there wasn't any follow up. You can use Cedric Han's chan_unistim as a 
reference. Cedric has reversed engineered quite a lot of the UNISTIM 
protocol. His code is still missing a few things, wrt the newer 
phone/Succession. I've been working on adding support for newer devices 
to chan_unistim. Also, I have written a simple standalone dissector 
(requires MS .NET) for my own testing. Contact me off list if you wish 
to have a copy.
