wifi calling in Pixel 4a 5g, I can't hear

Yup same.  My specifics is that my 5G signal, well, TMobile signal all together, is week near at my location.

I'll turn wifi calling off, but miss regular calls.  With wifi calling on, I can receive a wifi call, pick it up, I can't hear anything, bit while the call is still active, turn off wifi completely, the call switches to cellular and it works.

This works until I realize because my cellular signal is garbage, I miss a call.

Have any of you tried changing the preferred cellular network connection type to not 5G, so LTE?

This is a problem for me, as well, with my Pixel 4A 5G.  Very annoying and unacceptable.  Disabling Wi-Fi isn't an option for me as T-Mobile coverage is so poor here that I can't use the cellular network for calls.

Is everyone using Google Wi-Fi? I can’t remember if this happened when I was using my ISPs router or not.

Google wifi here with the issue.  Verizon FiOS ISP. Router issue perhaps?

Same issue with my pixel 4a 5g.  Disabled wifi calling completely.

Might be an issue with corporate network setting - (need to open some ports)

Seemed to fix my issues..

@chrispix can you explain how to do this?  i see the link but don’t see clear instructions.  thnx

There's a google bug tracker open on this.  I encourage everyone here to go comment there too since it seems to be stagnant (although it is "assigned" to someone at least).

Both my wife and my Pixel 5's have this same issue where we can't hear the other caller sometimes, but switching off wifi "fixes" it immediately.  Both purchased unlocked from Google and we had them on Verizon briefly for a few months with zero wifi calling issues until we switched to T-Mobile.

This used to be a daily problem with my 4a 5G.  Now that I upgraded to Android 12, it only happened once so far.  

Same issue on my Pixel 5a 5G.  Since it seems to be affecting the Pixel 4a 5G, Pixel 5 and 5a 5G and those 3 phones are all using the snapdragon 765G processer does that have something to do with the issue?  I switched from Verizon to T-mobile and having to restart my phone multiple times a day just to make phone calls is ridiculous. Sounds like a phone update from google is needed to address the issue.  I also reported to the Google bug tracker.

Pixel 5a with T-Mobile - wifi calling unusable b/c I can't hear anyone.  Live in rural location with spotty cell service so wifi calling is essential - I bought the phone based on this feature. Spectrum cable internet, up-to-date Tomato router, UniFi access point.  Fix please.
