Strange bug: Siri refuses to use speakerphone on WiFi calling

[jonstatt1]

I have found this most peculiar bug at least on my phone it is 100% reproducible

"Hey Siri. Call home on speaker"

Siri, responds that it is calling home on speaker but instead uses earpiece.

I have found this ONLY happens when the phone is connected on WiFi calling! If I turn WiFi calling off forcing the phone to use the mobile/cell network instead, then Siri does what it is told.

I can't imagine what bizarre coding error has resulted in this one! Has anyone else noticed this?

Yes same here!! There are some limitations when it comes to WiFi calling and maybe this is one of them. Do you get a strange busy signal as well with WiFi calling? Since adding WiFi calling I now get a voice saying the line is busy instead of the usual beep beep. Hopefully someone can chime in with some answers.
