Not so much as you may assume. I'd bet (not with much money, admittedly) that you can't get into the web interface with a telephone-digit variant of your password.

I'm not sure where in their architecture phone-keypad-compatibility lies, but it's quite possibly not even in any user-facing system.

In that case, the security of your password is not much reduced -- only if someone has access to that telephone-access system, and can do something bad with it.
