Question : Availble SIP Soft phones?

I have been trying to find a few SIP Soft phones for desktops to evaluate. So far I have found the Pingtel and obviously the Windows Messenger.  What I need to try to get a couple more.

Does anybody know where I can download any SIP Soft Phones for evaluation.  Particularly interesed in solutions that can handle Voice, Video and T.120/Data.

I know H.323 endpoints already do this but I have been tasked with investigating the potential for a SIP solution.

Any help is appreciated.
