For curiosity I went through the registration process and ended up with this:
Account Requested
Thank you for your request.
We will check your credentials and unlock your account soon. You will receive an e-mail as soon as your account is ready to use.
I used a real anonymous email address to see what I get after the initial email they sent that said much the same.
I doubt I’ll get anything useful.
It would be pretty slick though to be able to make adjustments via the phone after initial setup.
Edit: As expected…Signia said no. Of course for all I know they’re monitoring here or someone said something.
