However, the actual dialling of the EAGI–Enhanced Asterisk Gateway Interface EAGI is a slightly more advanced version of AGI, allowing the AGI script to interact with the inbound audio stream via file descriptor 3. See the documentation for the 'AGI' dialplan We need to stream the phone call audio to Google in real time using gRPC protocol. Includes a dialplan example to show how to interface the script as an AGI or EAGI This repository is an example of how to use Google Speech Recogntion in Asterisk to transcribe audio voice. Then you need probably check by tag other issues with AGI/python, for example this can be helpfull. Usually, AGI scripts are used to do advanced logic, communicate with relational databases (such as PostgreSQL or MySQL), and access other external resources. ; PlayFile: A flag to be set with the name of the file to be played.

Just to prove it, we’re going to cover AGI programming in I am testing EAGI for real-time voice analysis and have noticed that when I run for example “EXEC AMD” or “EXEC Background” application from the EAGI script, no audio flows on fd 3 while the app is running and starts to flow again when the app finishes. You can find a lot of information with a Google search of Asterisk EAGI <your language>. I think it is a pretty reasonable situation, no?
