[Freeswitch-dev] Freeswitch ESL application with audio stream

Hello! I’m not very experienced with freeswitch and audio streams so I would like some feedback I’ve set up a freeswitch server with a ESL application that records the caller’s audio. Then, on a separate service, I treat it and respond with audio files I generate with Text-to-speech. I’m thinking of setting up an audio stream on that service and exposing it so I can playback to the caller using mod_shout. Do you think that’s the correct approach or do you have any suggestion of modules I can look into? I also checked mod_rtmp but I’m not sure it could be helpful to me. Thanks in advance! :)
