[Q] Problem in playing an audio in an active call

Hi everyone,
First of all I am a new comer in the world of android and new to this forum. So I need guidance from experienced people like you guys.
I was trying to make an Auto Answering Machine in android. When there is an incoming call, the application should receive it and play an welcome message to the caller. I know its not possible to play the audio message in call stream. So my idea was to play the audio in loudspeaker, thinking that it'll be picked up by the microphone and the caller will hear it.
The problem is the microphone doesn't pick the sound from the speaker whereas at the same time it picks all other sounds from other sources. Hence the caller can't hear the welcome message. I didn't know what was the reason and after lot of searching I found out that it was due to "Echo cancellation" technique used in telephony, which is used to remove similar patterns. For example, when the receiver intentionally want to speak in loudspeaker, the speaker voice should not get propagated to the caller. Hence the technique of "Echo Cancellation" is used.
So my question is, is there any way I can overcome my situation? Can I stop the echo cancellation or any other techniques? I would really appreciate any kind of help.
I have the same problem

[Q] Hangouts Recorder?

I don't have a SIM card but I can make calls VoIP with Google Hangouts Voice. Is there an app that can record my calls? I know they exist for non-VoIP apps but none I tried work with Hangouts.
I tried a screen recorder that can record internal sound and microphone, but I get an error that says:
"Microphone Busy, Only one app can use microphone at a time. This is an android limitation. Close other app using the microphone (e.g. Google Now or Skype) or continue recording without audio"

I just found this thread, I am also looking for a solution for this, let me know if you found anything. I use google voice a lot but unfortunately you can not record calls when usin hangouts for voice calls, I will let you know if I find something.
