My wife has been using Google Voice [Moto X, 2nd Gen] for a few years, just for International Calls. Recently–maybe 2 weeks ago–her Google Voice calls would not go through; she would only get a “busy” signal. She’d try our land line [still have one], and the calls would go through.
As a test, I downloaded Google Voice to my Galaxy J3, and found that I could not make International calls either. Local calls go through.
We have lots of GV credit, have uninstalled/reinstalled the GV app on our phones, have cleared the app cache, have tried manually entering the digits, have shut down/restarted the phones, have tried initiating GV calls from the desktop computer…all to no avail.
There doesn’t seem to be a widespread outage, so I must be missing something obvious. Any suggestions?
