Could you explain the monitoring dialing status example?

[rinarakaki]

In this example, when call_status == "active" it immediately returns from (supposedly entrypoint) function, but in my understanding, the call_status should transition like "dialing" → "active" → "hangup". So if you implement like this, it never enters the call_status == "hangup" branch. Could you correct my understanding? Thanks.

start_time = perf_counter()
while perf_counter() - start_time < 30:
    call_status = participant.attributes.get("sip.callStatus")
    if call_status == "active":
        logger.info("user has picked up")
        return
    elif call_status == "automation":
        # if DTMF is used in the `sip_call_to` number, typically used to dial
        # an extension or enter a PIN.
        # during DTMF dialing, the participant will be in the "automation" state
        pass
    elif call_status == "hangup":
        # user hung up, we'll exit the job
        logger.info("user hung up, exiting job")
        break
    await asyncio.sleep(0.1)

logger.info("session timed out, exiting job")
ctx.shutdown()

I think you are right, we should fix this example code.
