I'm trying to solve a mystery for the last couple of days.
I have a mix of D70, D50 and D40 behind NAT. Server is in a
colocation, not a VPS.
For several years, everything was working fine, no issues. A few days
ago I started having problems at one particular site. NO CHANGES have
been made to this office network - same router, switch and internet
provider. No new equipment added or configuration changed (I only
upgraded the firmware and asterisk trying to solve the problem).
A few seconds after registration, the Digium phones will become
UNREACHABLE. Right after that, the entire VoIP network (where the
Digiums are located) will be also dropped - all other devices
(non-Digium) connected will be kicked from the asterisk box. There are
ObiHai, Yealink and Linksys at this location - all will be kicked.
The server remains operational and all other users/peers (not running
Digium phones) are up and running.
Don quite understand: above you say that all others phones are kicked
too and here you say they are up and running ... Also, UNREACHABLE and
kick are not the same for me.
Sip debug and tcpdump didn't show any relevant information to solve
the puzzle.
What is relevant: do you see SIP traffic coming from those
phones/location *AFTER* they are UNREACHABLE/kicked?
Is a fail2ban involved ?
