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. Sip debug and tcpdump didn't show any relevant information to solve the puzzle. I also replaced the router (twice, different models and firmware versions), PoE switch and cable modem. No success. IP is dynamic but the provider will only change it once a year. Qualify=yes (or no) didn't fix. Removing the password (deny/permit IP) also didn't. Running Asterisk 13.20.0, firmware 2.6.2. Any ideas where I should dig further? -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
