Maybe there were some static routes that disappeared

Ugh :(<br>
<br>
Sorry, I have no more ideas, then.<br>

I hope someone else comes into this thread with a

The new SIP trunks are replacing the IAX2 trunks to our other
Asterisk servers and use exactly the same network paths, that is why
I know it is not a network infrastructure issue. We did turn on IAX
debug and we only se the server trying to poke the other servers but
there is not response or any incoming traffic.<br>
