Demo Questions
Question 1
Refer to the exhibit. In an active SIP call between phone user A and phone user B, phone A initiates a call transfer to phone user C.
What are two results from this action? (Choose two.)
- Phone_A sends a SIP-REFER message to the Cisco UCM with Phone_C information in the Refer-To section.
- Phone_B sends a SIP-REFER message to the Cisco UCM with Phone_C information in the Refer-To section.
- As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the MOH, and the MOH audio is chosen from Phone_B User Hold MOH Audio Source settings.
- As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the music on hold, and the MOH audio is chosen from Phone_A Network Hold MOH Audio Source settings.
- As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the MOH, and the MOH audio is chosen from Phone_A User Hold MOH Audio Source settings.
Correct answer: AC
Question 2
Refer to the exhibit.
Users report that when they dial to Cisco Unity Connection from an external network, they cannot enter any digits.
Assuming only in-band DTMF is supported, what is a reason for this malfunction?
- The negotiated RTP port is outside of the range described by RFC, so inband DTMFs do not work.
- There is SIP Delayed Offer. DTMF is supported only in Early Offer.
- The rtpmap:0 value for the negotiated codec is marking DTMF as inactive.
- No DTMF is negotiated.
Correct answer: D
Question 3
An administrator is troubleshooting a one-way audio issue for a call that uses H.323 protocol in slow-start mode.
The administrator requests that the IP and port information of the Real-Time Transport Protocol traffic that had the one-way audio call is provided.
The H.225 and H.245 messages for one of the one-way audio calls are gathered and the call flow has not invoked any media resources.
Where is the RTP IP and port information for both sides found?
- H.245 Terminal Capability Set
- H.245 Open Logical Channel
- H.225 Connect
- H.245 Open Logical Channel Ack
Correct answer: B
