We have a 3CX Phone system version 12. I have successfully used 3CX Phone for Android, and 3CX Phone 3 for iPhone with it. When I use 3CX Phone 12 for iPhone, and try to call an extension or outside line, I get a "Forbidden" message and the call disconnects. This does not happen on the exact same iPhone with the exact same configuration under 3CX Phone 3. Here is the activity log events for the failed calls: Here is the activity under 3CX Phone 3: Any idea why this is happening? Anyone else using 3CX Phone 12 under iOS 7.1.1 sucessfully?
