Wifi calling not working

The wifi calling feature just stopped working at some point today.  We have next to no cell reception at home so we rely on wifi calling completely.  It was working fine at 9:00 am but I noticed at 3:00 pm I was unable to make any calls.  I have done and redone all the resets and troubleshooting tasks on both my device and my wifi router with no issues found.  It isn't just my device that it is not working on either, neither my daughter or my roommate can get it to work on their phones either.  We are all Telus subscribers on the same account.  

I have read in other posts that sometimes network issues can impede wifi calling but haven't been able to find anything stating a current issue in my area.   

Does anyone have any tips or insight into what's going on?
