I finally added fingerprinting to svmap. This gives it the ability to
guess what is running on a SIP network entity even if the user-agent
header is missing. You’re welcome to give it a try.
If you already have sipvicious:
$ svn update
If you don’t:
svn checkout http://sipvicious.googlecode.com/svn/trunk/ sipvicious-read-only
Any bug reports please send to me
