Have been using Asterisk as the PBX, But then, I am unable to get any response from the Vapi voice! Although the call is going throgh! Has anyone tried to integrate their custom BYO SIP, with Vapi? If yes how?

Hi there! I understand you're trying to integrate your Jio SIP provider with Vapi using Asterisk as your PBX, and while calls are connecting, you're not getting any voice response from Vapi. To help troubleshoot this issue, could you please share more details about: 1. Your current Asterisk configuration for the SIP trunk to Vapi (specifically the settings for

sip.vapi.ai

on port 5060)? 2. Are you seeing any specific error messages in your Asterisk logs when the call connects? 3. Have you configured authentication correctly? Vapi expects authentication credentials in the

Authorization

header with your SIP username. 4. Have you checked if your Asterisk server is properly configured to handle [SIP REFER messages](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336713212233515089), which Vapi uses for call transfers? 5. Which transcriber are you using in Vapi? Some users have resolved similar "no voice response" issues by [switching from Deepgram to another transcriber](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1343612796717371393) like Whisper or Azure.

The call seems to be getting connected by Jio, but then I cant hear anything from Vapi! Can you give me the exmple conf files for astersisk, so that i can set it up correctly?
