Cisco Exam 300-815 Topic 14 Question 70 Discussion

Actual exam question for Cisco's 300-815 exam

Question #: 70
Topic #: 14

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.)

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

BAsk the firewall administrator to change the ports to TCP.

CAsk the firewall administrator to change the range of UDP ports to 16384-32767.

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

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

Option D seems a bit too specific. Why not just go with the broader range in option A?

Option A seems like the most logical choice. Increasing the media port range in the SIP profile should allow for more flexibility and address the intermittent voice issues.

I agree with Roosevelt. Changing the range of media ports in the SIP profile or asking the firewall admin to change the UDP ports could help.
