DX70 - Changing call audio source?

Hello,

I've recently used the DX series SDK and successfully tested the example android applications. However, I'm trying to see if it's possible to send audio from an inputstream type into a Cisco call.

When I searched online I found that a normal Android device does not allow of modification of the outgoing audio in a call. You can only switch between physical microphone sources or possibly a bluetooth headset.

My question is:
Is there any way that I can send audio from a local file or inputstream type to the receiver end of a call on a DX70? I'm open to creative solutions.

Thanks for the help!

I've moved this post to the DX Series Community space so that developers following that space can reply to your post.
