android DTmf tone
<p>I am sending dtmf tone via this code.  </p>

<pre><code>String number="tel:+962791212121,2,3,3";
Intent c1= new Intent(android.content.Intent.ACTION_CALL, Uri.parse(number));
startActivity(c1);
</code></pre>

<p>It send perfect dtmf as this.  <em>2+<strong>(2 sec delay)</strong>+3+<strong>(2 sec delay)</strong>+3.</em></p>

<p>but I want to remove that 2 sec delay or I want to control that delay.</p>

<p>How can I control <strong>(2 sec delay)</strong>?
Or any other method to send dtmf tone during call?</p>
