How to Enable CDR & CMR on CUCM

How to Enable CDR & CMR on CUCM

The Call Detail Records (CDR) and Call Measurement Records (CMR,  also referred as “Call Diagnostics Records”) offer details for each phone call passing by the Cisco Unified Communications Manager (CUCM). In CUCM CDR CMR records are disabled by default, so that you have to enable them manually.

You can enable CDR and CMR in CUCM by following steps below:

How to Enable Call Detail Record (CDR) on CUCM:

  1. Login to administration page on Publisher CUCM. Click System -> Service Parameters menu.

2. Then select your server which has callmanager service enabled and then select Cisco CallManager (Active)

3. On System section find CDR Enabled Flag Parameter and set to True. If you’d like to see calls with zero duration, find CDR Log Calls with Zero Duration Flag (just below the CDR Enabled Flag)and set to True.

4. Do this for each CUCM Server if you have more than one server that has Callmanager service enabled.

How to Enable Call Measurement (CMR) on CUCM:

  1. On the same Service Parameter menu, go up and click Advanced.

2. Find the Clusterwide Parameters section, and change Call Diagnostics Enabled Parameter from Disabled to which option you wish.  

Note: Since CMR parameter is in Clusterwide Parameters, you don’t need to enable this on each server.

How to Get Wireshark Capture in CMS?

How to Get Wireshark Capture in CMS?

In this article, you can find steps to get Wireshark Packet Capture over Cisco Meeting Server (CMS).

While dealing with Cisco Meeting Server (CMS), you may encounter many errors such as audio / video packet loss, signaling problems, and you may need to listen to network traffic from time to time to fix them. In this article, you can find steps to get Wireshark Packet Capture in Cisco Meeting Server (CMS).

CMS Wireshark Packet Capture Steps:

  • First, connect to your CMS server via SSH to access the CMS MMP interface.
  • In some installations, CMS may have more than one network interface. So, after connecting, use the callbridge command to find out which interface to capture from:
Find Interface Using “callbridge” Command

To start the packet capture process, use the pcap command (in our example we will use the pcap a command):

Starting Packet Capture with “pcap a” Command
  • Once you start the Packet Capture process, re-create the traffic you want to listen to, and then use the Ctrl + C key combination to finish the capture process.

Note: The size of the .pcap file can be up to 100MB.

  • You can use an SCP program to download the generated .pcap file (in our example we will use WinSCP). Connect to the CMS using the username and password that you SSH connection with the SCP program, and find the corresponding .pcap file, and then download it to your computer:
Accessing the pcap File with WinSCP

That’s all 🙂

Cisco RJ-21 Pinout

Cisco RJ-21 Pinout

Cisco multi-port voice gateways have one or more ports for analog phones which is called RJ-21. Since the distance between the Cisco voice gateway and the phone distribution frame can be variable, you may need to make a special cable to connect these ports.

You can see the RJ-21 port and pin order used in Cisco multi-port analog voice gateways in the following image:

Cisco Webex Room USB Review

Cisco Webex Room USB Review

As you know in video conferencing and collaboration technologies, Cisco is the hardware and software manufacturer with the highest market share. However, as software-based solutions have emerged over the past 1-2 years, there has been an increasing demand for integrated video conferencing devices as well as audio and video transceivers. While Logitech took the lead in this market, there were many innovative products on the market (I also reviewed the most innovative Jabra Panacast in this article). Cisco will also want to take a share in this market that last January it made a serious introduction with its new product, Webex Room USB.

Cisco Webex Room USB is a device that turns any endpoint (Laptop, Desktop, SFF PC etc.) into a video collaboration center. The software you use does not even need to be Cisco, you can use this device with any collaboration platforms (eg. Microsoft Teams, S4B, Zoom, Slack, Jitsi etc.). Let’s examine the features of this device in more detail.

Cisco Webex Room USB Features

Cisco Webex Room USB is an ideal device for meeting rooms with 2-5 participants thanks to its 120 degree view camera. Basically, the device is in the form of a soundbar with embedded camera and placed on top of the screen. Apart from that, it has a remote control and a USB cable. There are also kits for display and wall mounting, a physical privacy cover for the camera, and two cables for HDMI and Ethernet connectivity. The prominent features of the device are as follows:

  • Camera Quality: Cisco Webex Room USB has a 4K UltraHD camera that can shoot video at 60 frames per second. It can automatically adjust the brightness and white balance supported by the 8MP image sensor for maximum clarity. With the artificial intelligence technology it contains, it has the feature to intelligently frame the image and a number of analytical functions for meetings so that everyone can be clearly seen by automatically detecting the meeting participants.
  • Sound Quality: There are integrated microphones and speakers on the device. Thanks to it’s automatic noise reduction feature, it can filter out distracting ambient sounds such as paper rustling and tea sugar mixing sounds. With the speaker design, it offers a more saturated sound experience, especially at low frequencies where human voice is dominant. To listen to the difference in sound with other manufacturers (Logitech), you can check out the video in this link.
  • Digital Signage Display: I think this feature is the most important feature of Cisco Webex Room USB that distinguishes it from other competitors. It can be used to turn connected PC displays into a digital signage when the device is not in use. You can use this feature for sharing corporate news, creating brand awareness, etc.
  • Content Sharing: It supports 4K content sharing as well as wireless content sharing via the web browser. In this way, you can find the opportunity to reflect your content on the screen easily.
You Can Also Use Webex Room USB As A Digital Signage Display

Apart from these, you can access more detailed technical features through the datasheet in this link.

Comparison With Other Vendors

As I said at the beginning, there are a few players in this market, especially Logitech. In the table below you can find comparison with the two most common devices:

Product /FeatureCisco Webex Room USBLogitech MeetUpPoly Studio
USB Camera, Speakers & microphoneYesYesYes
Intelligent Camera & SoundYesNoNo
Device SettingsYes (via Webex Control Hub)NoNo
Wireless content Sharing Yes (via Webex or a web browserNoNo
Digital Signage Display Yes (via Webex Control Hub) NoNo

In the video below you can see how you can connect Webex Room USB to your computer and use it as an audio and video device:

Cisco Webex Room Kit Mini USB

Cisco Webex Room USB Price

If you have a software solution or a service subscription for your video calls, you can get this device, which provides a Webex Room Kit Mini quality call experience, at a list price of $ 2,750 (of course, this is not the actual sale price). Compared to the Webex Room Kit Mini, the price of Room USB is less than half the price of Mini.

Last Words

For small businesses and organizations that want to switch to video communication, it might be a good idea to start with Cisco Webex Room USB and then turn it into a Room Kit Mini with an upgrade kit. In this way, you can both keep the initial investments very low and have a solution that will provide the highest level of video call experience.
