Was that a human caller or an automated caller? I noticed something similar on my Yu line.  <br><br>I&#39;ve received a couple of network initiated calls from YU in the last few days. If I recall well, it was their &quot;Dunda tunes&quot; IVR system (that Ring Back Tones service) announcing some Yadda Yadda.  <br>
<br>I&#39;m planning on blocking the &quot;Calling Number&quot; should the calls get out of hand &amp; when I get the chance.<br>
