I knew of a few vendors that had products under development (as of 
August).  I don't know where things stand now however.  Others might.

You will probably not see IPsec support however.  The VoIP world is 
backing SRTP (bearer) and TLS (SIP signaling) over IPsec.  A lot has to 
do with IKE or, key management in general.

IPsec works just fine.  In fact, the softphone on my laptop talks to the 
corporate network via the same IPsec connection netscape does all the 
time.  Of course, used in this way, things are not 
encrypted/authenticated end to end.
