Hi, i'm executing "att_xfer"

So...

A Bridge to B, and i make a att_xfer using B uuid, to C...

When B in call with C.

A gets silence, i try to play a music with playback, and its work, but i can't execute anything until music is played.

And when B digits *, to start with transfer, i try to play a music to A uuid, but i can't receive other DTMF events from B...

Is there a way to play a music to A, when i make a att_xfer?

Then when att_xfer is done, de music stop to play....

I try to use "fifo" too, but is the same result, i can't get B leg DTMF events after...

i'm not using lock in this Events...

I'm just want to play some music or sound to A, until he is waiting for B or C to take the call
