Internal Audio Parameters

Server Administration

RTCP itself does not improve QoS, but provides information to help identify where problem areas might be.

You cannot change the telephone’s RSVP or RTCP parameters directly on the telephone or by TFTP or DHCP administration. The only way to change these parameters is on the H.323 telephones, and such a change requires appropriate switch administration. See your Avaya Media Server administration documentation for more detail. You cannot change these parameters on a SIP IP telephone.

The AUDIOENV variable provides control of some internal audio parameters in the 4600 Series IP Telephones. Avaya does not recommend that customers set these values. In certain situations, particularly in noisy environments, Avaya Tier 4 engineers might recommend that you set the system parameter AUDIOENV.

AUDIOENV is an index into a table that impacts four internal variables:

Table 6: Internal Audio Variables

Variable	Description	Possible Values

AGC_Dyn_Range	AGC dynamic range.	0 for a typical office environment (+/-9dB), 1
		for +/-12dB, 2 for +/-15dB, and 3 for +/-18
		AGC Dynamic range variation.

Exp_thresh_Hd	The expansion	The expansion threshold for the headset has

	headset.	environment, 1 for call center applications,
		and 2 for “other” audio environments.
Exp_thresh_Hs	The expansion	The expansion threshold for the handset has
	threshold for the	a default value of 0 for a typical office
	handset.	environment, 1 for call center applications,
		and 2 for “other” audio environments.

Tx_Gain	Transmit gain.	Transmit gain has a default value of 0 for
		normal transmit gain, 1 for +6dB of gain, and
		2 for -6dB of gain.

AUDIOENV is calculated as:

AUDIOENV= (27 * AGC_Dyn_Range) + (9 * Exp_thresh_Hd) + (3 * Exp_thresh_Hs) + Tx_Gain, which results in a range of 0 to 107.

Set AUDIOENV 0 is the nominal setting (0,0,0,0)
