I'm leaning towards Option D, which is to remove the 'disable-early-media 180' configuration from the SIP UA. This would allow the gateway to properly handle the 180 response with SDP and play the ringback correctly.

Okay, let's take a look. Option A seems to be disabling the early media for the 180 response, which could potentially fix the issue. Option B is disabling early media in the SIP UA configuration, which is also relevant.

Hmm, this question seems to be testing our understanding of SIP gateway configurations. From the details provided, it seems like the issue is with the gateway not handling the 180 response with SDP correctly, which is causing the local ringback not to work.
