Yealink W60B fails to register after VPN breaks and reconnects

[Jim Shaflucas]

I have a 3CX installation with multiple sites connected via VPNs using Mikrotik routers.
For some reason, whenever one of the sites loses connectivity to the 3CX server (the VPN breaks and reconnects), the W60B phones fail to re-register. All the other phones come back online at the sites including the W56P DECT phones and T46S phones. It's just the W60B phones that have this problem. The only way to get them to re-register is to log into the web interface of the W60B and reboot it. Then it is good until the next "outage" which could be anything from a power failure or an internet disruption. I can recreate the issue if I restart the Mikrotik router at the sites that have W60Bs. This happens at all locations that have W60B phones. Firmware is updated to the latest and 3CX is running the latest version and service packs.

Anyone else having this issue?

So the reg interval is set to 120. Phone never re-connects after the interval. I tried updating the firmware to W60B-77.83.0.25.rom which was just released but having the same issue.
gbrown100...I am basically having the same symptoms. You can get into the base over the VPN but nothing will get it register unless you restart. I am going to run a wireshark as well so see what is going on with it.

@Jim Shaflucas did you manage to do a wireshark? I haven't been on site and they haven't had a connectivity drop since. If I get a spare moment I will go force the issue but my client is a seasonal business and are closed so it involves extra effort getting on site, shutting off alarms etc.

This is still an issue for me, I have had to remotely log in and reboot the base stations again... I can't believe only two of us are seeing it!

@Jim Shaflucas do you still have this issue?

 

[Jim Shaflucas]

Yes it is still an issue. I haven't done a wireshark yet though.

Manually config one of the phones/extensions and simulate a vpn disconnect and reconnect.

@3cxnub Mine are not over VPN and I know the internet had dropped between last time they went wrong and this time as I have the ISP data on line drops. To me right now it appears to be a time thing. It's pretty much 30 days since the last problem.
