Implementing Cisco Collaboration Devices (CICD, legacy) — Question 7

An SCCP IP phone places a call to a SIP phone that is registered to the same Cisco Unified Communications Manager Express. During the active call, call waiting indicates a second call is incoming to the handset, but the user decides to ignore it. In this scenario, what is the combined total number of signaling conversations and media flows that used the SCCP phone as an endpoint?

Answer options

• A. 2
• B. 3
• C. 4
• D. 5
• E. 6

Correct answer: B

Explanation

In this scenario, the SCCP phone has one signaling conversation for the initial call to the SIP phone and one additional signaling conversation for the incoming call waiting notification. This results in a total of three signaling conversations (including the media flow for each call), hence option B is correct. The other options do not account for the correct number of signaling and media flows combined.
