Report of SBC losing registration

[AlexDBarrett]

We are seeing an SBC disconnect at a clients installation.
The PBX is Hosted with 3CX and have installed a Raspberry Pi 4 for 10 extensions.
After seeing disconnections SBC was moved to a Server VM, we are continuing to see disconnections.

Our suspicion is an Internet connection issue however we need some facts prior to approaching the provider.

How long in time does a PBX need to loose an SBC before it reports and registers again?

Regardless the provider has now admitted there is an issue with provision however Would still like to know the interrupt time before SBC shows as unregistered.

3CX will send the email notification at any "up" event, so even a momentary disconnect. For "down" events it can take up to 5 minutes. That's not exactly what you asked but hopefully helpful. I'm pretty sure the answer to your question is "any disconnect" without a time.
