    <KeyItem>
    <Key>PushToTalk</Key>
    <URL>RTPMTx:Stop</URL>
    <URLDown>RTPMTx:239.1.2.3:20480</URLDown>
    </KeyItem>

    With the above sample XML snippet, when the corresponding IP Phone XML service is invoked, the PTT button available with wireless 7921 IP Phone device will act as per below:

    When the button is pressed it will start transmitting and once released, transmission is stopped.

    Hi David,

    Do you mean that when the button is pressed, the "RTPMTx:239.1.2.3:20480" command is executed. And when the button is released the "RTPMTx:Stop" command is executed?

    I have another question.

    If we want to do Push To Talk feature, when no button is pressed, the phone should listen to a multicast channel.

    So we should use the following codes:

    <!-- it is a snippet of another.jsp -->
    <KeyItem>
    <Key>PushToTalk</Key>
    <URL>http://ip:port/another.jsp</URL>
    <URLDown>RTPMTx:239.1.2.3:20480</URLDown>
    </KeyItem>

    where another jsp would execute "RTPMTx:Stop" and "RTPMRx" when first loaded.

    Is it true?

    Thanks!!

    Tony
