Welcome to the community LambertW!
We didn't get any alert of any network issue in your area. Did you try to restart your phone by any chance?
Did you have a chance to check our new Network Aid section on the website? You can click here to view it.
I checked network aid and there is no issue in my area but i still can't make a call pass 30secs without it failing. incoming calls are perfectly fine however.
Are you sitll experiencing this same issue this morning? Can you try completing a manual network selection to see if that makes a difference?
