wanpipe-freeswitch-config-freetdm-analog

    The wancfg_fs configuration script will generate basic freetdm.conf and freetdm.conf.xml files for the analog card. For more advanced options, you can manually edit freetdm.conf and freetdm.conf.xml.

    File format

    freetdm.conf

    All I/O related parameters are set in freetdm.conf.

    [span wanpipe <span name>]

    name => freetdm
    trunk_type => <trunk type>
    group => <group name>
    <channel type>-channel => <physical span number>:<channels>









    span name:     any string as long as the span name used in freetdm.conf and in freetdm.conf.xml are the same

    trunk type: possible values are: fxs, fxo

    group name: any string.

    channel type: possible values are: fxs, fxo

    physical span number: This should match the TDMV_SPAN  parameter in your /etc/wanpipe/wanpipeN.conf

    channels: Specify which timeslots within this physical span you want to use.

     

    freetdm.conf.xml

    Unlike PRI and BRI, analog does not have signaling channels. So in this file, the user mentions which context will be assigned to which span.

    <configuration name="freetdm.conf" description="FreeTDM Configuration">                 

    <!-- General FreeTDM Configuration options -->
    <settings>

    <param name="crash-on-assert" value="no" />

    </settings>

     

    <!-- list of ANALOG spans -->
    <analog_spans>

    <span name="[span name]">

    <!-- switch related parameters -->
    <param name="dialplan" value="XML" />
    <param name="context" value="default" /> 

    </span>

    </analog_spans>

     

     

    Sample configuration files.


    Configuration Options

    In freetdm.conf

    1. Gains

    In freetdm.conf.xml

    2. Callerid
    3. Callwaiting
    4. Polarity reversal
    5. Polarity delay
    6. Enable analog option
    7. Digit timeout
    8. Max-digit

     

     

     

     

    Gains

    With the gain option, you can try to increase or decrease the signal strength

    rxgain => X
    txgain => Y

    X and Y can be positive or negative values

     

     

    Tonegroup

    tonegroup is a two letter country code which the user can specify, to select the tone zone

    <param name="tonegroup" value="tonegroup" />

    tonegroup : us (United States), sg (Singapore), ru (Russia)

     


    Callerid

    Enable/Disable callerid

    <param name="enable-callerid" value="true" />

     


    Callwaiting

    Enable/Disable callwaiting

    <param name="callwaiting" value="true" />

     


    Polarity reversal

    Here there are several options for polarity reversal. The user can perform hangup on polarity reversal or answer on polarity reversal

    Enable/Disable answer on polarity reversal

    <param name="answer-polarity-reverse" value="true" />

     

    Enable/Disable hangup on polarity reversal

    <param name="hangup-polarity-reverse" value="true" />

     


    Polarity delay

    This option is for fxo only

    <param name="polarity-delay" value="delay" />

    delay: is the time in millisecond

     


    Enable analog option

    There are a few option which can be enabled on the analog by setting the following values 

    <param name="enable-analog-option" value="option" />

    option : call-swap, 3-way(three-way calling)

     


    Digit Timeout

    This option is for fxs only.

    <param name="digit-timeout" value="timeout" />

    timeout: amount of time allowed to input digits

    Max Digit

    This option is for fxs only.

    <param name="max-digits" value="max_digit" />

    max_digit:maximum of digit allowed
