Voice is not coming from server to phone on EC2 deployment | Working on local environment

[BhargabSixthSens]

Hi, I am facing an issue.
When I deploy this to EC2 voice is not coming from server to my phone.
It is working on local environment.
I am getting response from gpt and text to speech service is also working I think.

What could be the issue?

Hello, @BhargabSixthSens

I have the same result, I make the connection and it completes and connects but it is silent on the gpt side.

This is due to start event is not coming in hosted server.
For some reason first few events are missing. so you will miss connected and start event.
So the following code won't execute

if (msg.event === 'start') {
        streamSid = msg.start.streamSid;
        callSid = msg.start.callSid;
        
        streamService.setStreamSid(streamSid);
        gptService.setCallSid(callSid);

        // Set RECORDING_ENABLED='true' in .env to record calls
        recordingService(ttsService, callSid).then(() => {
          console.log(`Twilio -> Starting Media Stream for ${streamSid}`.underline.red);
          ttsService.generate({partialResponseIndex: null, partialResponse: 'Hello! I understand you\'re looking for a pair of AirPods, is that correct?'}, 0);
        });
      }

One workaround I found

You can pass the callSid from body as a param in wss link here

And here you can pass a second param (ws, req)

use req to get params and callSid

wss://${process.env.SERVER}/connection/${req.body.callSid}

app.ws('/connection/:callSid', (ws,req) => {

const {callSid} = req.params;
...

use callSid to set gpservice callSid
and in media event you will get streamSid set it in streamService
something like this

else if (msg.event === 'media') {
   if (!streamService.streamSid) {
        streamService.setStreamSid(msg.streamSid);
        recordingService(ttsService, callSid).then(() => {
          console.log(`Twilio -> Starting Media Stream for ${streamSid}`.underline.red);
          ttsService.generate({partialResponseIndex: null, partialResponse: 'Hello! I understand you\'re looking for a pair of AirPods, is that correct?'}, 0);
        });
    }
    transcriptionService.send(msg.media.payload);
}
