[asterisk-users] Client Asterisks can't connect when main Asterisk reboot
Hi all, we are running some Asteriks (version 13 on Debian Stretch) as VM/kvm in datacenter and have trunks with other Asterisk (v1.8 11 or 13) instances behind FW. Problem we face is that when we reboot the DC Asterisks, the trunks (SIP or IAX) become alive from DC Asterisks to clients ones but UNAVAILABLE the other way. In clients logs we see Registration for 'XXX@ourDCAsteriks' timed out, trying again (Attempt #5550) or UNREACHABLE in case of no registration or IAX Sometimes a restart from client Asterisks is enough (SIP or IAX reload has no effect) to recover the full trunk, but in most cases we have to reboot the client server :( If we use a VPN (OpenVPN) between Asterisks, no problem.
