SBC's are disconnecting/reconnecting daily

[Alphabetic]

Good morning

After updating to v18 of the PBX (Saturday morning just gone) I've found for the past 2 days the 3 SBCs on there are apparently disconnecting and reconnecting all at the same time.

There's no rhythm to it, Sunday was 05:44 and today was 08:27

Unfortunately all SBCs are in low mode so this is the only thing I can pull off one of them for now:

I've put one of them in verbose mode and I hope to capture why.

Has anyone experienced this?

I meant PBX. You would still need SBCs if they weren't on the same premises...

If they're all disconnecting at exactly the same time I would take a look at what was going on with your PBX at the time rather than the SBCs.
