You will need to look at the packets to see what the replies are

It sounds like it could be a Do not disturb gone wrong

But if you see the sip request going to the right place you can see the error
response and that might provide more information

Hi Duncan Turnbull,

It is a newly created PJSIP extension with default settings. I have 
never configured Do Not Disturb settings before.

Could it be something else?

Do I need to run tcpdump on the Asterisk PBX server again?
