Maybe D—disabling moved-temporarily often fixes voicemail ring-to-busy issues.

Option D seems more plausible here since the problem looks like the SIP moved-temporarily message is causing the call to fail over to voicemail properly. Disabling that supplementary service often stops the call from timing out and giving a busy signal after ringing for a while. The other options don’t directly address the SIP signaling behavior that blocks voicemail. So, turning off the sip moved-temporarily feature is likely the right fix to let calls get forwarded to voicemail without the timeout.

Guessing C here since allowing voicemail module connections seems like the right move to get calls routed correctly to voicemail instead of just timing out.

It’s D because the issue sounds like the SIP moved-temporarily message is blocking voicemail forwarding, so turning off that service stops the busy signal after ringing.

This one’s tricky, but I think C fixes voicemail connection.
