WiFi Calling - "IPService has stopped"

[yapkuen]

The last two days I've been getting an "IPService has stopped" crash message when trying to make or receive calls using WiFi calling. Rebooting the phone seems to fix it, but I haven't been able to go more than 24 hours before the problem recurs. I get poor cellular signal penetration into my office building, so turning off WiFi calling while at work isn't an option. My phone is stock, not rooted. Anyone else seeing this error?

I have the same problem! very frustrating! I have no cell reception in my home office, so I setup to make calls via wifi, and getting the same problem. Have you found a solution yet? My Carrier is TMobile
and phone is HTC One
