Hello, I have an issue with Ring Central where every outbound call I attempt to place does not show in the app. Yet the call goes ahead. I can hear the call ringing, but no screen shows up telling me I am on an active call - I cannot put the call down, or mute or anything. If I press the green phone button again, all it does is statrt a new call on top of the existing call. I then get cut off a call 1-2 minutes in. Please can you help?

I am running RingCentral App on iphone
