Just want to know what 1 frames means??
is it 160 bytes
and asterisk core has max 1000 frame does that means astersk can buffer 160000 byytes??
and 900 frame means 144000 byes of media??
The maximum number of frames the channel driver will keep in its queue waiting to be sent to the core is about 1000. That’s about 20 seconds of audio with a 20ms packetization rate. When the queue gets to about 900 frames, the channel driver will send a MEDIA_XOFF event to the app. The media the app sent just prior to receiving MEDIA_XOFF will be processed in its entirety even if the resulting frames cause the queue to reach 1000 but any data the app sends after that will probably be dropped. When the queue backlog drops down below about 800 frames, the channel driver will send a MEDIA_XON event at which time it’s safe to start sending data again.
