In an effort to, well try anything I could think of. I created a new Inbound and Outbound trunk just like the others are setup.I was using 4x new number allocating 2x numbers for inbound and 2x for outbound.
I then setup the same Inbound and outbound rules just as I already have, other than they are going to a Queue that is not in use by Agents or Office workers. I am the only agent in this Queue.
Test a call from an outside line, call goes into the Queue, rings my desk phone, and I am able to answer the call with no issues. So it looks like its working fine now on the new trunk that I created. Event log showed no errors or issues. Below are the Activity Log for the time of the call, it looks like a whole lot of failing but I do not look at the event log very much.
In short adding the a new trunk for inbound and outbound seems to have fixed the issue. I play on deleting one of the current trunks after office hours and re-adding it and see if this fixes the issue. On the new Trunk I used the settings that
NickD_3CX suggested in OPTIONS.
Unless anyone has any other suggestions I will update after I try deleting and re-adding trunks. I'm still wondering what changed from Sunday to Monday. We do have update turned on for Monday morning but the 15.5.13103.5 (v15.5.0) update was not installed and I manually did that. Then updated the phones FW. The issue was present before I ran the 15.5.13103.5 (v15.5.0) update.
