I have android 5.0.1, and everytime I want to make an international call I get the above alert. I have turned on international calling under settings gear. But I do not see any 'Call options' tab uner Setting Gear. Also, everytime I enable international calling, it seems it had not really done so. Every time I press international calling under Setting, it asks to enable again. Reinstalled the app a couple of times. Somehow, it seems to work from my wifes iphone 5s. Frustrating that Spectrum tech support doesn't seem to know what the solution is.
