asterisk users - Jan 2024 - chan_iax2.c:4739 __auto_congest: Auto-congesting call due to slow response

I'm using asterisk-16.30.1

When I try to call another asterisk server over IAX I get a busy signal,

chan_iax2.c:4739 __auto_congest: Auto-congesting call due to slow response
     -- IAX2/192.168.143.1:4569-656 is circuit-busy

Asterisk-16.16 is working normally, no congestion error.

There is not enough information for anyone to really help or comment on 
this.
Dialplan and IAX2 configuration on both sides of the trunk?
CLI output on both sides with iax2 debug enabled?
