Three different SBC devices were reported to 'have changed status to Up' simultaneously

[Leo_B]

Gentlemen,

We run three 3CX setups, all with SBC devices deployed on customers' sites. Today we started receiving multiple messages reporting all three SBC instances to 'have changed status to Up'. No 'Down' message was spotted, though, while the notifications outburst lasted just a couple of minutes. No customer reported connectivity issue, too. So the question is, have someone ever experienced such a weird behavior before?

3CX Version: Enterprise Annual 16.0.1078
Server OS: Debian 9 v16.0.655
Is the 3CX Server Hosted: no
IP Phone Make/Model/Firmware: Yealink T58A v58.85.0.5
Provisioning Method: SBC
Trunk Provider: Vitelity
Has the Firewall Checker passed: YES
Are custom Phone Templates being used: NO

Yes, many people have. Either your 3CX instance has having connectivity issues, or your customer (if all in the same region or same ISP) was having connectivity issues back to the 3CX instance.

Well, considering all three SBC are assigned to 3CX instances hosted by the same VPS provider, your explanation covers the issue perfectly. Thank you for response!

The SBC "up" email triggers on each connection. The "down" email takes I think 5 minutes of downtime to trigger. so short outages will result in an up but no down.
