I feel like I'm overlooking something simple here.
Phone A extenstion is forwarded to Phone B extension.
When someone calls Phone A's extension, and Phone B ultimately forwards this to voicemail, Unity Connection plays the greeting of Phone A (based on the Called Number).
Is there a way for Unity Connection to play Phone B's voicemail (based on the last redirecting number) in this scenario?
Never mind I found the parameter of Use Last (Rather than First) Redirecting Number for Routing Incoming Call
under System Settings -> Advanced -> Conversations
Just so you know that's the default behavior you'll find on CUC and Unity, always use the original called number to determine which mailbox to reach.
