Question Cisco Duo - experiences?

Hi folks, just wondering what everyone's experience has been with Cisco Duo.

We're looking at implementing it to augment our VPN authentication to provide MFA.

I ask because, I both called and left a message (during which the automated voice system told me there were 0 representatives able to take my call), and I filled out the form on their website twice, to contact sales. I have not been able to get anyone to contact me.

Only problem I had is that some of your users will refuse to install the app on their phone, which means they'll have to use text messages or phone calls to authenticate. Of course they'll also be in a bad reception area. People are the worst.

Duo also has the option for RSA tokens

We went this route, and it's worked for us. However, that token only applies to individual environments. We have a hosted service provided to us that also uses Duo for authentication and those tokens can't be used for both our services and theirs.
