Solved calls disconnect after 32 seconds after v16 update 5

[proboscis]

Hi, we were running v16 update 4 with no issues. After updating to update 5 for the new app, our calls are disconnecting after 32 seconds. Error is "ACK is not received". Firewall checker shows all green. our firewall shows nothing dropped. I've updated before with no issues so wondering what could be happening. Anyone have any ideas? Thanks.

So the pbx is on-prem running as a VM on a hyperv host. I reverted back to update 4 and everything is working again, no changes to firewall. So I'm wondering if it's related to the update itself. thanks

ok found the problem. Updating 3CX is like re-installing, you have to go through the initial setup every time. This time, it was pulling our default public IP address (x.x.x.170) instead of what we use for our phones (x.x.x.172). So our firewall was dropping it. Every time I upgrade, I normally just click "next, next, next" through the setup. Guess I'll just have to keep a closer eye on it next time

Hello,

If you are upgrading from V16.x.x to V16.x.x you should not require a reinstall (for Windows OS)

It can be upgraded in place. If you were moving from V15.x to V16.x it would require a reinstall then (again for Windows OS only)
