When CTS 1300 has 3 microphones connected and 3 tabletop mic's configured in CUCM, the microphone test fails with the following error:
"Could not access calibration data. Microphone Calibration not performed"
Tested this with configuration in CUCM to be 6 table top mic's with only 3 mic's connected and the microphone test DOES NOT fail.
Part of CSCtf87238 : Found in CTS 1.6(3) and fix in 1.7(0)
