Explanation/Reference: Route Plan Report
The route plan report lists all assigned and unassigned directory numbers (DN), call park numbers, call pickup numbers, conference numbers, route patterns, translation patterns, message-waiting indicators, voice mail ports, and Cisco CallManager Attendant Console pilot
numbers in the system. The route plan report allows you to view either a partial or full list and to go directly to the associated configuration windows by clicking the Pattern/Directory Number,
Partition, or Route Detail fields.
In addition, the route plan report allows you to save report data into a .csv file that you can import into
other applications. The .csv file contains more detailed information than the web pages, including directory numbers for phones, route patterns, pattern usage, device name, and device description.

Viewing Route Plan RecordsThis section describes how to view route plan records. Because you might have several records in

yournetwork, Cisco CallManager Administration lets you locate specific route plan records on the basis of specific criteria. Use the following procedure to generate customized route plan reports.

Step 1Choose Route Plan > Route Plan Report.
The Route Plan Report window displays. Use the three drop-down list boxes to specify a route plan report that meets your requirements.
Step 2 From the first Find drop-down list box, choose one of the following criteria:

Refer to the exhibit. You have received a trouble ticket that two engineers at the HQ site tried to conference at a user location at the Branch site and the ad-hoc conference failed.

Further investigation reveals that the remote user can occasionally be conferenced in. Phones are configured to use G.711 for intra-site calls and G.729 for inter-site calls. All phones at the remote site are configured to use MRGL_Branch, which contains only the media resource group named BRANCH.

What should be done to correct this issue?

A. The software conference bridge CFB_2 should be removed from the Branch media resource group. B. The hardware conference bridge CFB0012005FEEF1 should be listed first in the Branch media
resource group so it is utilized if it is available.
C. Additional hardware conference resources should be added.
D. The number of sessions allowed per conference should be increased.

Correct Answer: A Section: (none) Explanation

The software conference bridge can support only G.711

Using thevoice rtp send-recvCommand to Establish Early Two-Way Audio
The voice path is established in the backward direction as soon as the RTP stream is started. The forward audio path is not cut through until the Cisco IOS gateway receives a connect message from the remote end. In some cases it is necessary to establish a two-way audio path as soon as the RTP channel is opened, before the connect message is received. To achieve this, use thevoice rtp send-recvglobal configuration command you can have a situation where you only have a 1 way path to listen to

announcements, it’s usually used to fix 1-way audio issues when

they’re not supposed to happen intentionally Also helps on DTMF issues
