A better way to manage audiosocket protocol.
go get github.com/pablodz/fastaudiosocket- Read packages
All packages sent by asterisk to audiosocket are read by the function ReadPackage in the file audiosocket.go. Now the package payload in ulaw contains 160 bytes and for pcm 320 bytes.
- Write packages
All write packages are 320 bytes + 3 headers. The main difference here is that we need to handle from audiosocket server the timing to sent each packet (head+payload) to asterisk on each 20ms. Write only accepts 320 bytes of payload in pcm linear 16 format. (Remember to remove the headers if you are sending the chunk in streaming)
Check the examples folder to see how to use the package.
