Follow the following steps from C:\Program Files\Cisco - ciscotsp.txt file. The directions might be a little different for you as I have CCM3.3(3), but if the following steps don't do the trick for you then follow the steps appropriately from "ciscotsp.txt" file from above location.
For Windows XP:
From Control Panel execute the "Add Hardware" utility. Click the
"Next" button. Select "Yes, I have already connected the hardware"
Radio button. Click Next. Select "Add a new Hardware device" from the list.
Click the "Next" button. Select "Install the hardware that I manually
select from a list" radio button. Click the "Next" button. Select
"Sound, video and game controller" when prompted for hardware type.
Click the "Next" button. Click the "Have Disk" button when prompted
to "Select a Device Driver". Click the "Browse" button on the
"Install from Disk" window. Browse to
C:\Program Files\Cisco\Wave Drivers and select the file "OEMSETUP".
Click "Open" to install the Cisco Wave Driver and select OK.
Highlight the "Cisco TAPI Wave Driver" in Select a Device Driver window
and select 'Next'. Select 'Next' in "Start Hardware Installation" window.
If Prompted for "Digital signature Not Found" click on "Continue Anyway"
button.
When prompted for "Install from disk 1" for file avaudio32.dll, choose
Browse button and select path "C:\Program Files\Cisco\Wave Drivers"
and click Open to install the avaudio32.dll.
When prompted to reboot your machine, do so.
