Implementing Cisco Collaboration Devices (CICD, legacy) — Question 70

Two IP phones configured in the same office have a phone call in progress when the Call Manager they are registered to fails. Which result is true?

Answer options

• A. The call remains active, and the Cisco IP Phones enable SIP proxy mode for RTP.
• B. The call disconnects after the RTP/RTCP keepalive between the IP phones and Call Manager fails.
• C. The call remains active, but features such as MOH and Transfer are unavailable for the rest of the call.
• D. The call is immediately disconnected. C

Correct answer:

Explanation

The correct answer is C because even though the Call Manager has failed, the call can remain active between the two IP phones, but advanced features are not supported without the Call Manager. Option A is incorrect as SIP proxy mode does not apply in this scenario. Option B is wrong because the call does not disconnect solely due to the keepalive failure. Option D is not accurate since the call can continue despite the failure of the Call Manager.
