I feel like the failover timer being set to 0 seconds could definitely cause problems, but I need to double-check that detail.

The P-Asserted Identity header sounds familiar, but I can't remember if disabling it would cause this exact issue.

I think the Baltimore root certificate is crucial for the SBC to function properly, but I can't recall if it was specifically mentioned in our practice questions.

I remember studying about Location-Based Routing, but I'm not sure if it would prevent calls from being placed.
