SHORETEL IS NOW PART OF MITEL. See how powering connections in the cloud is now brilliantly simple.

Audio Adjustments for ST IP Phones

Scenario

Note: For 400 series handsets audio adjustments, please refer to the Maintenance Guide for your installation.

The audio levels for the handset, headset and speaker are set to default values when the phone boots. These values can be overridden by configuration file settings.

The phone supports multiple configuration files, and the last setting encountered in a configuration file wins.

More Information

The text line must be formatted and saved exactly in this format:

HeadsetLevels 6144,183,258,409,649,1028,1630,2899,6491,10288,14333,917,13,13

No spaces except between HeadsetLevels and the first number.
No empty line at top of text area.
Only H and L are capitalized.

When saving:  Save As "
shore_<MAC_ADDRESS>.txt"
Use quotes exactly as above, leave out < and >, and MAC_Address should have NO DASHES, only the numbers!!!

If you deviate from the above format, the file will not work!

Resolution

Global Audio Setup

The base configuration file for each phone type is created by the installer, so although new values may be set in these files, they will be lost when the system is upgraded. Customized audio levels should be set in customized configuration files rather than the base configuration files. Below is a table showing phone name, model and file names:

Single IP Phone Audio Setup

You can use shore_<MAC_ADDRESS>.txt to add the Custom Audio Level for each Individual Phone. You will create a new file called shore_<MAC_ADDRESS>.txt -- where MAC_ADDRES is the actual MAC Address or Serial Number of the IP Phone.

(Example: “shore_aaBBccDDeeFF.txt”) Note You do not use the < >

Parameters that can be configured:

Default Values can be found in the maintenance guide under the heading "Configuration for IP Phones"

Format for entry into configuration files:
HandsetLevels: TxGain, RxGain1, RxGain2, RxGain3, RxGain4, RxGain5, RxGain6, RxGain7, RxGain8, RxGain9, RxGain10, Side Tone, Handset DTMF Attenuation, Call Progress Attenuation
HeadsetLevels: TxGain, RxGain1, RxGain2, RxGain3, RxGain4, RxGain5, RxGain6, RxGain7, RxGain8, RxGain9, RxGain10, Side Tone, Headset DTMF Attenuation, Call Progress Attenuation
RingerLevels: RxGain1, RxGain2, RxGain3, RxGain4, RxGain5, RxGain6, RxGain7, RxGain8, RxGain9, RxGain10
SpeakerLevels: TxGain, RxGain1, RxGain2, RxGain3, RxGain4, RxGain5,RxGain6, RxGain7, RxGain8, RxGain9, RxGain10, Speaker DTMF Attenuation,

User-added image
The Plantronics CS50 wireless headset provides its own side tone, plus “+” inserts 20 ms delay between the headset and the phone, which causes some people to say they hear echo when using the Plantronics headset; in this case, headset side tone may need to be reduced. When you speak, Plantronics reduces the gain on the speaker by -24dB; but when you stop speaking, the gain is turned up, and you can hear the last little bit echoed in your ear.

For example, inserting the following line in s2custom.txt or s6custom.txt and rebooting the phone increases the headset volume settings 11 dB at the highest setting, which may be required in noisy environments:

Headset levels: 6144,183,258,409,649,1028,1630,2899,6491,10288,14333,917,13,13


Inserting the following line reduces the headset side tone by 6 dB, which some CS50 users prefer:

Headset levels: 6144,183,258,365,516,728,1029,1631,2303,3254,4596,643,13,13

Minimum gain values are 0 and maximum are 32536. Setting values very high may saturate the speaker and create poor sound quality. You can change gains on an individual phone by changing the configuration files and then rebooting the phone. Eventually, all phones on the system obtain these values when they reboot.
