Core Issue
In the Cisco CallManager 4.x Cluster, after the Customer Response Solution (CRS) is installed on a subscriber server, the JTAPI subsystem fails to start. The log located at c:\ program files\wfavvid\log\ciscomivr.log contains the unspecified errorcom.cisco.jtapi.CiscoRegistrationExceptionImpl: At least one media capability must be specified error message.
A restart of the CRS Engine has no effect on this issue.
Resolution
This error message in the log indicates that it is a failed install, and that the codec does not get set in the registry for some reason. Check this location in the CRS server registry:
HKEY_LOCAL_MACHINE\SOFTWARE\CiscoSystems,Inc.\CRS\Properties\application.MIVR.properties.com.cisco.dialog.cod
ec = G711ULAW64K,G711ALAW64K
If it is not there, add the G711 codec with these steps:
- Stop Node Manager on the CRS server.
- Choose Cisco CallManager > LDAP > CCN Apps > Clusters > Custer Specific > Properties.Files
- On the right, locate the application.mivr.properites key, and delete it.
- Choose CRS Registry > HK LM > Software > Cisco Systems INC > CRS > Properties, and choose application.medt/MADM/MCVD.properties.
- Locate com.cisco.dialog.code, and copy the value string.
- Choose application.MIVR.properties, and change the com.cisco.dialog.codec value to the one copied in the previous step.
- Restart the Node Manager service in Microsoft Windows services.
If the JTAPI subsystem still fails to come into service, complete these steps:
- Use the media in order to uninstall the CRS.
- Make sure that these registry keys are removed:
HKEY_LOCAL_MACHINE\SOFTWARE\CiscoSystems,Inc.\CRS\Properties\application.MADM.properties
HKEY_LOCAL_MACHINE\SOFTWARE\CiscoSystems,Inc.\CRS\Properties\application.MCVD.properties
HKEY_LOCAL_MACHINE\SOFTWARE\CiscoSystems,Inc.\CRS\Properties\application.MEDT.properties
HKEY_LOCAL_MACHINE\SOFTWARE\CiscoSystems,Inc.\CRS\Properties\application.properties
HKEY_LOCAL_MACHINE\SOFTWARE\CiscoSystems,Inc.\CRS\Properties\application.MIVR.properties
- Use a new cluster profile name in order to reinstall CRS.
- Run the JTAPI Update Utility in order to verify the JTAPI client.
- Confirm the codec is now installed.
