/* HOW TO audio?
|
|
|
|
Audio flow has two ways:
|
|
|
|
* from channel to the upper layer
|
|
-> sound from mISDN channel
|
|
-> announcement from vbox channel
|
|
|
|
* from the upper layer to the channel
|
|
-> sound from remote channel
|
|
|
|
Audio is required:
|
|
|
|
-> if local or remote channel is not mISDN
|
|
-> if call is recorded (vbox)
|
|
|
|
|
|
Functions:
|
|
|
|
* PmISDN::txfromup
|
|
-> audio from upper layer is buffered for later transmission to channel
|
|
* PmISDN::handler
|
|
-> buffered audio from upper layer or tones are transmitted via system clock
|
|
* mISDN_handler
|
|
-> rx-data from port to record() and upper layer
|
|
-> tx-data from port (dsp) to record()
|
|
* VboxPort::handler
|
|
-> streaming announcement to upper layer
|
|
-> recording announcement
|
|
* VboxPort::message_epoint
|
|
-> recording audio message from upper layer
|
