•G.728/iLBC: 3.9 MOS LQK

•G729A/AB: 3.7 MOS LQK

Note		• Cisco Voice Transmission Quality (CVTQ) does not support wideband (7 kHz) speech codecs,
		because ITU has not defined the extension of the technique to wideband. Therefore, MOS LQK
		scores that correspond to G.711 performance are reported for G.722 calls to allow basic quality
		monitoring, rather than not reporting an MOS score.
		• Reporting G.711-scale MOS scores for wideband calls through the use of CVTQ allows
		basic-quality classifications to be indicated as good/normal or bad/abnormal. Calls with high scores
		(approximately 4.5) indicate high quality or a low packet loss, and lower scores (approximately 3.5)
		indicate low quality or a high packet loss.
		• Unlike MOS, the conceal ratio and concealed seconds metrics remain valid and useful for both
		wideband and narrowband calls.

	A conceal ratio of zero indicates that the IP network is delivering frames and packets on time with
	no loss.

Cleaning the Cisco Unified IP Phone

To clean your Cisco Unified IP phone, use only a dry soft cloth to gently wipe the phone and the LCD screen. Do not apply liquids or powders directly on the phone. As with all non-weather-proof electronics, liquids and powders can damage the components and cause failures.
