  • Adjusting Volume on phones

    How to adjust audio levels on IP phones by Ed Basart:



    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. 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:



    ---------- -------- ------------- ------------- -----------------
    --

    ShorePhone Name on Model Name on Base Custom

    Name Top of Barcode Label Configuration File Name

    Phone Underside of File Name
    c:\Inetpub\ftproot\

    Phone

    ---------- -------- ------------- ------------- -----------------
    --

    210 210 S1 shore_s1.txt s1custom.txt

    210A 210 S1A shore_s1a.txt s1custom.txt

    530 530 S2 shore_s2.txt s2custom.txt

    560 560 S6 shore_s6.txt s6custom.txt



    There are four sets of audio levels that can be custom configured:
    headset, handset, speaker and ringer. Below are the default values
    for each type:



    HandsetLevels
    5157,183,258,365,516,728,1029,1631,2303,3254,4596, 917,13

    HeadsetLevels
    6144,183,258,365,516,728,1029,1631,2303,3254,4596, 1375,13

    RingerLevels 130,258,410,649,1029,1631,2584,4096,6492,10284

    SpeakerLevels
    4096,258,410,649,1029,1631,2584,4096,6492,10289,16 306,13



    Here are the parameter definitions:



    HandsetLevels
    TxGain,RxGain1,RxGain2,RxGain3,RxGain4,RxGain5,RxG ain6,RxGain7

    RxGain8,RxGain9,RxGain10,SideTone,Handset DTMF
    Attenuation

    HeadsetLevels
    TxGain,RxGain1,RxGain2,RxGain3,RxGain4,RxGain5,RxG ain6,RxGain7

    RxGain8,RxGain9,RxGain10,SideTone,Headset DTMF
    Attenuation

    RingerLevels
    RxGain1,RxGain2,RxGain3,RxGain4,RxGain5,RxGain6,Rx Gain7

    RxGain8,RxGain9,RxGain10

    SpeakerLevels
    TxGain,RxGain1,RxGain2,RxGain3,RxGain4,RxGain5,RxG ain6,RxGain7

    RxGain8,RxGain9,RxGain10,SideTone,Speaker DTMF
    Attenuation





    The "TxGain" parameter sets the level of the audio transmitted from
    the phone onto the network. The "RxGain" values correspond to each
    of the 10 volume setting levels shown when one adjusts the volume on
    the phone. "SideTone" is the audio picked up from the microphone
    and transmitted to the speaker (speakerphone, handset or headset
    speaker) that provides feedback to the user that the phone is
    working speaking. Customer experience has shown that sometimes the
    RxGains are not high enough and need to be customized for an
    individual system. SideTone gain is very subjective, and is
    sometimes lowered and sometimes raised. DTMF Attenuation sets the
    receive DTMF level that the phone user will hear.



    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, and in this case headset side tone may need to be
    reduced. When you speak, Plantronics does reduce 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:



    HeadsetLevels
    6144,183,258,409,649,1028,1630,2899,6491,10288,143 33,1375,13



    The same levels could be used for "HandsetLevels", and also for the
    210 phone. Inserting the following line reduces the headset side
    tone by 9.5 dB, which some CS50 users prefer:



    HeadsetLevels
    6144,183,258,365,516,728,1029,1631,2303,3254,4596, 460,13



    Minimum gain values are 0 and maximum are 32536. Setting values
    very high may saturate the speaker and create poor sound quality.



    N.B.: You can change gains on an individual phone by changing the
    configuration files and then rebooting that phone. But eventually
    all phones on the system will obtain these values when they
    eventually reboot. We do not currently have the ability to
    indivually configure ShoreTel IP phone.

    Great post, I ran into this issue last week and would have loved to have had this guide.

      I've picked up some Plantronics CS70N (wireless) and P351N (wired) headsets. One user already had a CS50. The new CS70's exhibit some echo even after considerable time tweaking the various volume settings.

      A few questions: Any data on CS70 side tone, delay values, or adjustments to either on the headset/base?

      How linear are the settings 0-32536? surely not the 0.01db/point that your adjustment of 915 (from 1375 to 460) might indicate!

      Any change on release 7.5, particularly relating to "individualizing" phones? The wired installs don't need much tweaking and we have to strike a balance here!

        speaking of this topic, has anyone done this sucessfully? Our operator uses a plantronics headset and it is hard to hear her talk. It would be great to be able to make it louder.

          Hi Charles, we are using 115, which file do you think we can change to increase the speaker volume(Shoretel 8). COuld you also give me what commands can I type in to increase the volume
          thanks a lot

            Are there additional paramaters (i.e., a fifth paramater set) on the 565 phone for the bluetooth headset?

              No, the HeadsetLevels applies to bluetooth on the 565.

                here are the additional file names for the family of ShoreTel IP phones

                c:\Inetpub\ftproot\
                210 210 S1 shore_s1.txt s1custom.txt

                530 530 S2 shore_s2.txt s2custom.txt

                212k 212k Shore_s12.txt S12custom.txt

                565 565 S6C shore_s6c.txt s6ccustom.txt

                Remember when adjusting the levels on the phones, the average human ear will notice a 3dBm difference.

                Use caution when adjusting these levels over +5dB not to cause distortion to the handset/headset and +6dB over on the TXgain.

                RXGain Levels
                Value = Gain
                130 = -30dBm
                183 = -27
                258 = -24
                365 = -21
                410 = -20
                516 = -18
                649 = -16
                728 = -15
                916 = -13
                1029 = -12
                1372 = -9.5
                1631 = -8
                2303 = -5
                2584 = -4
                3254 = -2
                4096 = 0
                4596 = +1
                5156 =+2
                6128 =+3.5
                6492 = +4
                10289 =+8
                16306 =+12

                TX Levels
                Value Gain
                4096 Flat 0dBm
                6144 = +1
                8192 = +2

                      Min Ringer Volume Possible?

                      Anyone know of a way to set the absolute minimum ringer volume allowed on a 230? Seems that we have some workgroup users who have found a workaround for being logged into the workgroup against their will by just silencing the ringer on their phone (so that the call rolls to the next user in the workgroup).

                        Does any one know how to set the last volume to be non-zero

                        We are trying to disable the users ability to turn their phones ring volume down so low they cant hear it

                        We have edited the RingerLevels in s6custom and set the last 5 (left most 5) to the same value but it is still possible to set the phone to be silent :-(

                          Our site consists of a large number of IP 110 phones where the Speakers are mainly used for paging. We inserted this line (in the s0custom.txt file) to force all IP 110 phones to have a loud unadjustable volume level when receiving an intercom page:

                          SpeakerLevels 4096,16306,16306,16306,16306,16306,16306,16306,163 06,16306,16306,13,13

                          In my experience, the "SpeakerLevels" should be followed by a single space, followed by the numbers. It never seemed to work for us if it was separated by a line break / CR. Once I discovered that, it was simple!

                          (Edit: I notice that the forum software sometimes inserts an extra space in the numbers shown above. There are no spaces between any of the numbers, and no spaces before or after any commas separating the numbers. If you are copy/pasting any of the settings on these pages, make sure to remove the extra spaces after pasting.)

                            I didn't think IP110's had speakers...IP115's maybe?

                              The IP110's do have speakers! However, they are not speaker phones. Pages/Intercoms do play on the speaker. Also, you can use PCM to put a call on "speakerphone" on the IP110 where you can hear the call through the speaker (but they can't hear you because there is no mic on the phone). Perfect when waiting on hold for long periods when you don't want to cradle the receiver with your shoulder and head.
