The error that is repeated through most of that log is ..
10/23/2020 9:05:11 PM - Leg L:8436.3[Line:10008>>ELECTED_PHONE] is terminated: Cause: 404 Not Found/INVITE from OPERATOR_IP_ADDRESS:5060
So...it appears you are sending a number, it is reaching your provider, and your provider is responding with a 404 message. Because you have removed the numbers, I have no idea in what format they are being sent, but, it is probably something that your provider does not like.
Do any outbound calls work?
I would check with your provider to confirm what format they want to see. If you think that the didits you are sending are correct, then contact them, ask them to look at a call attempt, and then tell you what is not right.
