-- Auto fallthrough, channel 'SIP/XXXX-00000000' status is 'CHANUNAVAIL'

Good morning, sir,

We currently have an asterisk server, and unfortunately,
He starts to crash, and he doesn’t connect to the trunk anymore.
The only way to fix this is to change the ip.

Do you have any idea where that might be coming from, because our supplier says it’s not coming from them.

The configuration has been checked several times.

Thank you in advance,

Yours sincerely, Damien

did you check firewall? fail2ban ?

what errors are you getting?

I found the solution for the host to block our ip because we were always connected to the other server. That’s it and now it’s fixed.
