Haha, it's like Cisco is playing a game of SIP charades with us. The answer has to be B, otherwise it's just going to be a never-ending loop of 183 messages.

But wouldn't configuring midcall-signaling passthru on Cisco Unified Border Element also solve the issue?

I think the correct answer is B. Disabling the 'Early Offer support for voice and video calls' on the Cisco UCM SIP profile should resolve the issue, as the customer is seeing a delayed offer SIP INVITE being sent.
