If I have my phone in hand and it was already open to a number dial pad then maybe it's easier to press 1,2,3. But often, even when I"m already in call, I have to (1) press a side button to turn screen on, then (2) look to find button to press to bring up dial pad, before (3) I look to press 1,2,3. I hardly think saying "customer support" (without diverting my eyes or attention) instead is "way too much effort" in comparison. In fact, I just used similar voice command in automated call ten minutes ago because it felt like _less_ effort than bringing up the dial pad. With home automation I expect it would be even stronger in favor of voice interface, because I would almost never have a phone in hand with home automation app in foreground with display on.
