Hi There community,
I hope that who is reading this is fine,
About this case, some days (not a specific pattern) I’m having recurrent SIP Peer disconnections, on my LAN, MPLS and WAN net links with two different Asterisk physical hardware.
Peer X is Lagged
Peer X is Unreachable
Peer X is Reachable
Like a recurrent loop between those states.
I can’t find any log, Warning, Error or Notice that helps with this, when restarting the service everything seems normal
2 x Asterisk certified/16.8-cert3 in HP G8 physical hardware
1 x WAN Network (1 IP per server)
1 x LAN Network (1 IP per server)
2 x MPLS Networks (1 IP per server and MPLS)
4 NICs per Server
Does anyone have experienced something similar?
I don’t understand why just certain days of the year this happens if i haven’t moved any configuration of sip.conf, since we have iptables+fail2ban we don’t think that this is an attack but I’m not sure.
Edit1: ICMP seems fine, this happens only with Asterisk SIP OPTIONS (I don’t want to disable it)
Any advice or ideas will be greatly appreciated
If further information is required please let me know so i can retrieve it.
