A. Configure Cisco Unified Communications Manager regions.
B. Configure transcoding within Cisco Unified Communications Manager.

I agree with DrVoIP
Branch phone is capable of G.729 and can send the call over the WAN. CUCM should be able to convert between G.711 and G.729 with Region configuration. I think correct answer is A
much confusion as to correct answer as some report B and others report C. The trick is in the question. The all must traverse the WAN as G.729, therefore you can not transfer at the branch. You send media to the Voice Mail at HQ as G.729 and transcode remotely at HQ. this suggests that B is the correct answer. – DrVoIP.com
