Chapter 6 Cisco Unified Serviceability Alarms and CiscoLog Messages Warning-Level Alarms Cisco Unified Serviceability Alarm Definition Catalog CallManager/CallManager Severity Warning Parameter(s) Media Resource List Name(String) Recommended Action If all the resources of the Annunciator are already in use, check to be sure that all the Annunciators that belong to the Media Resource Groups of the indicated Media Resource Group List and Default List are configured and registered in all the applicable Unified CM nodes of the cluster. To check the registration status go to the Media Resources > Annunciator menu and click the Find button. It will display all the Annunciators with their status, device pool, and so on. Check the status field to see whether it is registered with Unified CM. Note that the display on the status field is not a confirmation that the device is registered to Unified CM. It may happen in a Unified CM cluster that the Publisher can only write to the Unified CM database before the Publisher goes down. Because the Subscriber may not be able to write to the database, the devices may still display registered in Unified CM Administration after they are actually unregistered. However, if the Publisher is down that should generate another alarm with higher priority than this alarm. The Annunciator allocation can fail due to codec mismatch or capability mismatch between the endpoint and the Annunciator. If there is a codec mismatch or capability mismatch (such as the endpoint using IPv6 addressing but Annunciator supporting only IPv4), an MTP or transcoder should be allocated. So, if the MTP or transcoder is not allocated then either MediaResourceListExhausted (with Media Resource Type as Media termination point or transcoder) or MtpNoMoreResourcesAvailable alarm will be generated for the same Media Resource Group List and you should first concentrate on that. The Annunciator allocation may even fail after checking the region bandwidth between the regions to which the held party belongs and the region to which the Annunciator belongs. Increasing the region bandwidth may be a solution to the problem, but that decision should be made after careful consideration of the amount of bandwidth you're willing to allocate per call between the set of regions. You'll need to weigh different factors such as the total amount of available bandwidth, the average number of calls, the average number of calls using the Annunciator, approximate bandwidth use per call, and so on, and accordingly calculate the region bandwidth. Another possible cause is that the bandwidth needed for the call may not be available. This can happen if the Annunciator and endpoint belong to different locations and the bandwidth that is set between the locations is already in use by other calls. Examine the bandwidth requirements in your deployment to determine whether bandwidth between the locations can be increased. However, note that increasing the bandwidth between these two locations means that you may need to reduce the bandwidth between other locations. Refer to the System Guide, SRNDs, and related Unified CM documentation for more details. Be aware that reducing the bandwidth or removing the higher bandwidth codecs from configuration may result in poor voice quality during call. Consider increasing the total amount of network bandwidth. ApplicationConnectionDropped Application has dropped the connection to CTIManager. TCP or TLS connection between CTIManager and Application is disconnected. OL-22523-01 Cisco Unified Communications Manager Managed Services Guide 6-201
