Is it possible to originate several outgoing calls with Asterisk taking several media streams from some program's outputs (or from ALSA/etc playbacks or from FIFO-pipes)? Fully automated solution, no human intervention required.
Issue
I have software which generates several (separated) audio streams. It can stream into ALSA/OSS/PulseAudio devices or FIFO-pipes (named pipes).
I need to resend this audio to my STT/ASR service provider via SIP (the only interface supported by provider) continuously.
Current workaround
My current test case is to record short files and use them with simple call-files like this one:
Channel: SIP/asr.provider.com/12345
Application: Playback
Data: chunk-filename-here
MaxRetries: 2
All works fine, but I need to make this process continuous (dial on start and keep connection alive as long as possible). I guess I need to replace Application: Playback with other appropriate application in call-files or in my dial-plan context.
UPD
As follows from chan_oss and chan_oss docs, both of them are not suitable:
With 1.2.x versions of Asterisk, only one OSS channel can be created and only one call can be placed to/from the OSS channel at a given time.
