I have a server that had been operating for a few years now with IAX2 trunks to several other servers. Since yesterday all IAX2 trunks now say UNREACHABLE. No configuration changes have been made and no upgrades have been done. The server is running 11.16.0 (yes, we are planning upgrades but lets solve this first). The server has a USB
ethernet adapter that got disconnected yesterday by accident and since it was reconnected we started having the problem. We have rebooted many times and even replaced the USB adapter but still the same issue, and the USB adapter is not the main ethernet link to the local network, it is just for a link to a provider. So far the only thing different is that the receive queue for port 4569 is not zero like all the other servers:
udp 128760 0 0.0.0.0:4569 0.0.0.0:*
Basically all packets for IAX2 are getting stuck in the queue. Any suggestions?
