Trouble making outbound calls (Circuits are busy. . .)

Having some trouble making outbound calls. Inbound is working fine but outbound gets me a “All Circuits are busy now, please try your call again later” message.
I have spoken to our provider who says they don’t see the calls even reaching their system meaning it is something on my end. Below are the logs when trying to make an outbound call. I have x’ed out numbers.

Any ideas? Been wrestling with this for days and I’ve been up and down forums hahaha
Let me know if any other info is needed.

Seems to me that the username or password is not correct for the trunk.

Thanks for your help. One of my colleagues ended up fixing the issue. Not yet sure what he did but I will find out and post it on here as soon as I know.
