Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 63

Between which two DTMF relay methods does the Expressway support interworking? (Choose two.)

Answer options

• A. unsolicited notify
• B. RFC 2833
• C. KPML
• D. passthrough
• E. H.245 user input indication

Correct answer: B, E

Explanation

The correct answers are B and E because RFC 2833 and H.245 user input indication are the DTMF relay methods that the Expressway can interwork with. The other options such as unsolicited notify, KPML, and passthrough do not provide the necessary interworking capabilities with Expressway.
