|
|
|
* This is called from ast_frame_free if AST_FRFLAG_FROM_DSP is set. This occurs
|
|
|
|
|
|
|
|
* because it is possible for the dsp to be freed while someone still holds a reference
|
|
|
|
|
|
|
|
* to the frame that is in that dsp. This has been known to happen when the dsp on a Zap
|
|
|
|
|
|
|
|
* channel detects a busy signal. The channel is hung up, and the application that read the
|
|
|
|
|
|
|
|
* frame to begin with still has a reference to the frame.
