I've seen only where people have stated they have been able to make this setup work but cannot find any specific instructions. I have found instructions on configuring the VPN on the ASA with no problems but when I go to connect the SPA525G2 I get the error "failed to obtain webvpn cookie". Googling says this is a certificate error, I am using a self-signed certificate on the ASA. Does that certificate needs to be loaded on the UC500 or the phone?
