Fop2 noise on whisper

Fop2 noise at the agent side when i try whisper

Comments

  • Hi,

    FOP2 does not handle audio in any way, all audio processing is done by Asterisk. Noise is usually not a problem, unless you have some analog part in the middle, from your report I will suspect of analog noise introduced (loose cable somewhere), that will get through on whispering or any other conversation for that matter.

    As FOP2 does not do audio processing, you will have to look into the Asterisk side of things for the problem.

    Best regards,

  • any idea why this happen only on whisper?

  • Hi,
    Sorry, I have no idea.. the concept of 'noise' seems strange. Maybe you are cut off, loosing packets, but I picture noise is actual static noise being injected somehow. In any case, FOP2 just starts the ChanSpy command on Asterisk, from then on, is all Asterisk.

    Inside the FOP2 configuration file (/usr/local/fop2/fop2.cfg) you can pass different parameters to chan spy when the whisper action is launched, that is all you can change in FOP2 config but I do not think that any parameter in ChanSpy would modify or alter that noise you hear. The default setting is:

    whisper_options="w"
    

    You can modify it, for example to avoid playing a beep, add the option "q"

    whisper_options="wq"
    

    Here is the list of options available on Asterisk 13:

    [Arguments]
    options
        b: Only spy on channels involved in a bridged call.
    
        B: Instead of whispering on a single channel barge in on both channels
        involved in the call.
    
        c(digit): 
            digit - Specify a DTMF digit that can be used to spy on the next
            available channel.
    
    
        d: Override the typical numeric DTMF functionality and instead use DTMF to
        switch between spy modes.
            4 - spy mode
            5 - whisper mode
            6 - barge mode
    
        e(ext): Enable *enforced* mode, so the spying channel can only monitor
        extensions whose name is in the <ext> : delimited list.
    
        E: Exit when the spied-on channel hangs up.
    
        g(grp): 
            grp - Only spy on channels in which one or more of the groups listed in
            <grp> matches one or more groups from the ${SPYGROUP} variable set on
            the channel to be spied upon.
    NOTE: both <grp> and ${SPYGROUP} can contain either a single group or a
    colon-delimited list of groups, such as 'sales:support:accounting'.
    
        n([mailbox][@context]): Say the name of the person being spied on if that
        person has recorded his/her name. If a context is specified, then that
        voicemail context will be searched when retrieving the name, otherwise the
        'default' context be used when searching for the name (i.e. if SIP/1000 is
        the channel being spied on and no mailbox is specified, then '1000' will be
        used when searching for the name).
    
        o: Only listen to audio coming from this channel.
    
        q: Don't play a beep when beginning to spy on a channel, or speak the
        selected channel name.
    
        r([basename]): Record the session to the monitor spool directory. An
        optional base for the filename may be specified. The default is 'chanspy'.
    
        s: Skip the playback of the channel type (i.e. SIP, IAX, etc) when speaking
        the selected channel name.
    
        S: Stop when no more channels are left to spy on.
    
        u: The 'chanprefix' parameter is a channel uniqueid or fully specified
        channel name.
    
        v([value]): Adjust the initial volume in the range from '-4' to '4'. A
        negative value refers to a quieter setting.
    
        w: Enable 'whisper' mode, so the spying channel can talk to the spied-on
        channel.
    
        W: Enable 'private whisper' mode, so the spying channel can talk to the
        spied-on channel but cannot listen to that channel.
    
        x(digit): 
            digit - Specify a DTMF digit that can be used to exit the application
            while actively spying on a channel. If there is no channel being spied
            on, the DTMF digit will be ignored.
    
    
        X: Allow the user to exit ChanSpy to a valid single digit numeric extension
        in the current context or the context specified by the ${SPY_EXIT_CONTEXT}
        channel variable. The name of the last channel that was spied on will be
        stored in the ${SPY_CHANNEL} variable.
    
    

    Best regards,

  • thank you for response
    i think agent hear other agents talking.
    im playing with chanspy arguments to see if something change

  • I still suspect that it is not noise, but 'analog interference'. Mics can pick up other people talking nearby.
    Best regards,
