[cisco-voip] CTL Client Install ?

[Dane]

I am working on trying to get the phone proxy feature of the ASA 8.0(4) working.

In doing so it lead me to needing some certificates off of my
CallManager 4.1(3).

Seems some of the certs I need are missing and that seems to be
related to the CAPF.

I do not have CAPF or CTL Provider activated on my publisher.  So I
started looking into doing this and it lead me to needing to install
the "CTL Client".  Well in reading about that it states I need a USB
security eToken?

Anyone with any experience in this, does all this sound right or I am
turning this into way more then it needs to be?

Do I have to get some USB security eToken from Cisco to do all this?

I just wanted to get the phone proxy feature working so that I could
have a VP's phone work from home.  :-)

I don't need to encrypt calls, I just need to authenticate phones.

Thanks!
