we have a running Asterisk 11.25.1 in a VM (qemu/kvm) OS being Debian
7.11 (wheezy), the host OS being the same.
Problem: when we restart the server (eg host + VM), all customers Asterisk connecting without a VPN (doesn’t matter which Asterisk version) are no more reachable. Same for IAX users.
On the host side, after restart, SIP packet are entering the host but NOT to the VM (tshark debug). In IAX, POKE packets sended by the VM are reaching the client Asterisk but no packet answer.
Everything is working again if we restart the customers Asterisk.
Any clue ?
