change the caller's number during an incoming call
<p>First I found a way to modify the called number during an outgoing call.
I tried the same for the caller's number during an incoming call, but the only thing I can do is read the caller's number, not change it. Can someone give me a hint?</p>

<p>My code in on receive so far:</p>

<pre><code>Bundle b = intent.getExtras();

Log.d(TAG, "Phone State: "+ b.getString(TelephonyManager.EXTRA_STATE));
incomingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.d(TAG, "incoming number: "+ incomingNumber);
</code></pre>

<p>How could I proceed?</p>
