Question 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 one-way 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.)

A : Go to the SIP profile assigned to these IP phones in Cisco Unified CM and change the range of media ports to 16384-32767

B : Ask the firewall administrator to change the ports to TCP.

C : Ask the firewall administrator to change the range of UDP ports to 16384-32767.

D : Go to the SIP profile assigned to these IP phones in Cisco Unified CM and change the range of media ports to 20000-22000.

E : Go to System Parameters in Cisco Unified Communications Manager and change the range of media ports to 20000-22000.

Answer: A,C

Question 2

The administrator requests that you provide the IP and port information of theReal- 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 IPand port information for both sides? (Note: This call flow has not invoked any media resources like MTP ortranscoders).

A : H.245 Terminal Capability Set

B : H.245 Open Logical Channel

C : H.225 Connect

D : H.245 Open Logical Channel Ack

Answer: B

A : Localize the calling and called numbers to PSTN format and globalize the calling and called numbers in the gateway.

B : Globalize the calling and called numbers to PSTN format and localize the calling number in the gateway

C : Localize the calling and called numbers to E. 164 format and globalize the called number in the gateway.

D : Globalize the calling and called numbers to E. 164 format and localize the called number in the gateway.

Answer: D
