title: Dual Channel Recordings
body: <p>I have a twilio sip trunk that's recording calls on a dual channel. However, as I'd like to transcribe offline - the solution I'm using (i.e. AWS transcriber) would like me to specify some details on the recording channels. Specifically, I need to specify which channel has the speech from the agent and which one has the customer's speech... Therefore my question is, among both channels (i.e. channel 1 and channel 2) which one is for the agent and which one is for the customer?</p>
  <p>Any insights are highly appreciated!</p>
  <p>Thank you.</p>
