Question
A company is installing Cisco Collaboration infrastructure and one of the requirements is that they must be able to communicate with many external parties that are using H.323 and SIP. Internally they want to register the endpoints only on SIP. Which functionality would describe the feature that needs to be enabled and where to achieve this?
Options
- AInterworking in Expressway-C
- BTranscoding in Cisco Unified Communications Manager
- CTranscoding in Expressway-C
- DInterworking in Cisco Unified Communications Manager

Explanation
Protocol Interworking on Cisco Expressway-C enables communication between H.323 and SIP endpoints by translating signaling between the two protocols. This is distinct from transcoding, which converts media (audio/video codecs). Since internal endpoints register on SIP and external parties use H.323 or SIP, Expressway-C acts as the interworking point. CUCM does not natively perform H.323-to-SIP protocol interworking in the same manner, making Expressway-C the correct answer for this use case.
