Exam 300-820 topic 1 question 4 discussion

Answer is Ajavascript:void(0)

By default, the Expressway acts as a SIP–H.323 and H.323–SIP gateway but only if at least one of the endpoints that are involved in the call is locally registered. You can change this setting so that the Expressway acts as a SIP–H.323 gateway regardless of whether the endpoints involved are locally registered. You also have the option to disable interworking completely. The options for the H.323 <-> SIP interworking mode are: • Off: The Expressway does not act as a SIP–H.323 gateway. • Registered only: The Expressway acts as a SIP–H.323 gateway but only if at least one of the endpoints is locally registered. • On: The Expressway acts as a SIP–H.323 gateway regardless of whether the endpoints are locally registered. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/admin_guide/X14-0-2/exwy_b_cisco-expressway-administrator-guide-x1402.pdf

Answer should be A

B. Transcoding in Cisco Unified Communications Manager. Using g.711 codec internally and 729 externally.

No transcoding is needed here, since there is no need to convert codecs, instead interworking from SIP to H.323 and vice-versa for the signaling.
