What is the function of the Cisco Unity Connection Call Handler?

1. A. routes calls to a user based on caller input
2. B. queues calls
3. C. allows customized scripts for IVR capabilities
4. D. searches a list of extensions until the call is answered

Correct Answer: A
A Cisco Unity Connection Call Handler is a software application that answers calls, plays greetings, and routes calls to users based on caller input. Call handlers can be used to create automated attendants, voice menus, and other interactive voice response (IVR) applications.
Call handlers are created and managed using the Cisco Unity Connection Administration interface. When creating a call handler, you can specify a variety of settings, including the greeting that is played, the caller input options that are available, and the destination that calls are routed to.
Call handlers are a powerful tool that can be used to create a variety of IVR applications. By using call handlers, you can improve the efficiency of your organization's communications and provide a better experience for your callers.
Here are some additional tips for using call handlers:
Use call handlers to create automated attendants that can answer calls and route them to the appropriate person or department.
Use call handlers to create voice menus that can provide callers with information or options.
Use call handlers to create interactive voice response (IVR) applications that can collect information from callers and process their requests.

To provide high-quality voice and take advantage of the full voice feature set, which two access layer switches provide support?

1. A. Use multiple egress queues to provide priority queuing of RTP voice packet streams and the ability to classify or reclassify traffic and establish a network trust boundary.
2. B. Use 802, 1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.
3. C. Implement IP RTP header compression on the serial Interface to reduce the bandwidth required per voice call on point-to-point links.
4. D. Deploy RSVP to improve VoIP QoS only where it can have a positive impact on quality and functionality where there is limited bandwidth and frequent network congestion.
5. E. Map audio and video streams of video calls (AF41 and AF42) to a class-based queue with weighted random early detection.

Correct Answer: AB
