In the last few months the app stopped making and receiving calls. It used to work perfectly but now I cannot make any outgoing calls and when someone calls me the call is routed directly to my carrier's voicemail, which defeats the purpose of a proxy number. I've checked all of my settings based on the information in all of the help guides and based on that these features should be working but they're not and I can't find an actual customer service line to fix the problem. It's useless now
