Build Application to Answer Phone Call and Delegate To iPhone's Phone Application
<p>We want to build an application that the user can interact with while taking a phone call.  The idea is that the user can do voice communication using the phone application of the iPhone and at the same time use our application to type and send additional data that is relevant to the call such as an e-mail address.  This is the scenario:</p>

<ol>
<li>User get's a call on the iPhone</li>
<li>The user clicks a button on our app to answer the call and let the phone application on the iPhone handle the phone call in the background.</li>
<li>Our application continues to run in the foreground so that the user can interact with our application to type and send data such as an e-mail address that is relevant to the call.</li>
</ol>

<p>Is there a way for our application to answer an incoming phone call and let the phone application of the iPhone handle the call in the background while our application continues to run in the foreground?</p>

<p>Thanks,
Prasanna</p>
