thanks @Shubham Bajaj

works fine without warm transfer, on normal transfer

I can see that the transfer function attempts to validate the call status before proceeding with the transfer. When this validation fails, it logs the error "Call is not in progress" which suggests the call might have already ended or was in an invalid state.

Hey Titus, could you write up an email to Twilio support team and put me in CC? Let's see what's going wrong here because we are sending the transfer at the right time, but they are saying according to logs the call has already been terminated. So it's either the user or Twilio who has terminated the call, but we have to find out the root cause of this. It's better to get in touch with them.
