1. Cisco SIP IP telephony is implemented on two floors of your company. Afterward, users report intermittent voice issues in calls established between floors. All calls are established, and sometimes they work well, but sometimes there is oneway audio or no audio. You determine that there is a firewall between the floors, and the administrator reports that it is allowing SIP signaling and UDP ports from 20000 to 22000 bidirectionally. What are two possible solutions? (Choose two.)(Select 2answers)

A) Go to the SIP profile assigned to these IP phones in Cisco Unified CM and change the range of media ports to 20000-22000.
B) Ask the firewall administrator to change the range of UDP ports to 16384-32767
C) Go to the SIP profile assigned to these IP phones in Cisco Unified CM and change the range of media ports to 16384-32767
D) Ask the firewall administrator to change the ports to TCP.



2. The administrator of ABC company is troubleshooting a one-way audio issue for a call that uses H.323 protocol (slow-start mode). The administrator requests that you provide the IP and port information of the Real-Time Transport Protocol traffic that had the one-way audio call. You gather the H.225 and H.245 messages for one of the one-way audio calls. Where can you find the RTP IP and port information for both sides?

A) H.245 Open Logical Channel Ack
B) H.245 Open Logical Channel
C) H.245 Terminal Capability Set
D) H.225 Connect



3. An administrator is troubleshooting call failures on an H.323 gateway via the CLI. To see signaling for media and call setup, which debug must the Administrator turn on?

A) debug H.246 asn 1
B) debug H.225 asn1
C) debug H.323 messages
D)



4. Which two statements are correct with respect to the Client Matter Code setting in the route pattern configuration? (Choose two.)(Select 2answers)
