Calls from my wife were going to voicemail. I disabled it and every other fixes that were available DND is of call forwarding is off call Barring and blocked calls are all off. Network reset all done but still won't connect to my phone just saying line busy. Help please.
Are you using WiFi?? If I connect to the house network... then just like you I lose all calls. If connect to my own network, everything works OK. Try turning off WiFi and see what happens.
