        <br>
        thanks for the reply. I forgot to mention i use blind
        registration so i specifically dont have directory entries so
        any other way to implement it with that, meanwhile ill try to
        wrap my head around the dialplan u provided.<br>
        <br>
        what i was thinking was suppose if any extension places a call
        then increment some counter and when that call ends reset it to
        0 so suppose if hes in a call and counter is at 1 then any new
        calls placed by anyone else check the counter for the first ext
        if thats called, if 1 then different ringback and if 0 then
        normal ringback<br>

        <div dir="ltr">Hi,</div>
        <div dir="ltr"><br>
        </div>
        <div dir="ltr">  To make it easier, let's call the main
          extension A, and the secondary extension B. When someone calls
          B and A is busy, you want the "call-waiting" signal to be
          heard.</div>
        <div dir="ltr"><br>
        </div>
        <div dir="ltr">Note: I've taken snippets from my dial plan and
          changed them in order to readable without my context; hence,
          they might not work on first attempt.</div>
        <div dir="ltr"><br>
        </div>
        <div dir="ltr">First, I've added a new parameter to the B's
          directory entry called "chk_ring" which has the value of B.</div>
        <div dir="ltr"><br>
        </div>
        <div dir="ltr">First, you have to tell mod_limit to track calls
          to/from the main extension (I am doing that for all
          extensions) with the following commands before calling the
          bridge application:</div>
        <div dir="ltr">      </div>
        <div dir="ltr">
          <div>
            <div>     &lt;action application="limit" data="hash
              max_calls ${dest} -1 HANGUP_USER_BUSY" /&gt;</div>
          </div>
          <div>This causes mod_limit to track the calls to that
            extension.</div>
          <div><br>
          </div>
          <div>BTW, it is adviseable to add also the following setting
            in order to count correctly when doing call transfer:</div>
          <div>&lt;action application="set"
            data="limit_ignore_transfer=false" /&gt;<br>
          </div>
          <div><br>
          </div>
          <div>Next, during a new call process you have to check the
            limit of A extension with the following:</div>
          <div><br>
          </div>
          <div>
            <div>
              <div>&lt;extension name="Intercom" continue="true"&gt;</div>
              <div>    &lt;condition break = "never" &gt;</div>
              <div>        &lt;action application="set"
                data="chk_number=${user_data(${destination_number}@${domain_name}
                var chk_ring)}" inline="true"/&gt;</div>
              <div>                &lt;action application="set"
                data="OrigDest=${destination_number}"  --- Save the
                original number</div>
              <div>                &lt;action application="limit"
                data="hash max_calls ${chk_ring} 1 ChangeRingBack" /&gt;<br>
              </div>
              <div>    &lt;/condition&gt;</div>
              <div>&lt;/extension&gt;</div>
            </div>
          </div>
          <div><br>
          </div>
          <div>And then add a ChangeRingBack extension:</div>
          <div>
            <div>
              <div>&lt;extension name="ChangeRingBack"
                continue="true"&gt;</div>
