How to _dial_ speed dial?

Hello.

I am defining entries in {MAC}-directory.xml with a speed dial number. Those entries show up under "Favourites" and can be selected and then dialed.

But can i actually somehow _dial_ those numbers? I don't want to go to some sub-menu to dial those entries. I mean, it's called speed _dial_.

Hardware: Multiple VVX410, 5.6.0.17325

Thanks.
