Clear2There is based in OKC? Rhodes have you heard of them?
Btw, USAG's website is one of the worst I have seen in years. Hello 2008, literally:

Yes, I am familiar with Clear2There. This line is typically marketed to be part of the portfolio carried by VoIP companies.
For small businesses - If you don't have a security integrator, but you have a phone system vendor, this is the dealer 'us-too' offering for those companies.
From past experience, it is not cheap or very powerful (limited VMS features, proprietary camera support, etc), but the major value for the SMB market was it could be purchased through and installed by the existing VoIP vendor.
Here's a link for supposedly free viewer software guaranteed to work on all USAG cameras.
FYI, I was able to download the camera finder from the usag website, though I did not run it.
