Hello there!
I have a problem with SIP traffic for VoIP. It is a HA cluster that has experienced that problem with the SIP traffic for phone calls. For a number of hours, SIP calls could not be made or received. Mismatches with the config between active and passive firewalls were found. Could that have been the cause for the problem with SIP traffic? Is it possible to find out why inbound and outbound SIP calls have failed for those hours? I mean, which logs should I look at?
Thanks in advance!

Hello,
In a HA A/P configuration, the passive device has its interfaces shut down and processes no traffic, so the config mismatch is a different issue. As for SIP, could be a lot of things.
Are you inspecting the traffic with AV/AP/URL, etc.?
What if you disable all inspections on the traffic does it work better?
Are you dropping any traffic?
I always start with the 'Unified' logs since they show me if its URL/Threat/Traffic etc.
Hope that helps.
