Take a look at the section "Cisco Agent Desktop Problem" from the below "Troubleshooting Cisco CRA Guide" which describes common problems with the Cisco Agent Desktop. For additional troubleshooting information about the Cisco Agent Desktop, refer to Service InformationCisco Desktop Product Suite 4.5 (ICD).

If the above doesn't help, please open a TAC case and provide the MIVR logs with debug level set to SS_TEL, SS_RM, SS_RMCM, SS_CM and agent.dbg trace with level 204 set will give more info.
Set the trace Level=204 in file C:\Program Files\Cisco\Desktop\config\fastcalllocal.ini
[Program Log]
Path=..\log\agent.log
Size=300000
[Debug Log]
Path=..\log\agent.dbg
Size=300000000
Level=204
The agent.dbg trace file will be in the C:\Program Files\Cisco\Desktop\log folder..
Regards
