<!--
  PhoneZero inline TeXML template — not a hosted bin.

  Call-create To (request field, not in this XML):
    sip:{PHONEZERO_FROM_NUMBER}@sip.voice.x.ai;transport=tls
  The Builder agent answers that To immediately.

  At call time the caller substitutes:
    {RESTAURANT_E164}       — callee PSTN E.164 inside <Dial>
                            (must be on the Telnyx outbound voice
                            profile attached to the PhoneZero TeXML
                            app — any name; enforcement is Telnyx,
                            not this XML)

  Task facts are NOT spoken here. Upload phonezero-task.json to the
  xAI collection (scripts/put-booking-file.sh) before this dial. The agent
  reads that file. Do not add <Say>.

  and passes the whole XML string as the Texml field on
  POST /v2/texml/Accounts/{account_sid}/Calls
  (request schema is oneOf: Url XOR Texml XOR neither — do not send Url
  when Texml is set).

  Flow: Pause 3s (welcome "PhoneZero is ready!" + collections_search
  on the SIP leg) → <Dial> the callee with an E.164
  callerId. The welcome is spoken on the agent's ear during this
  pause; the callee must not be bridged yet or a fast pickup
  hears it. After Dial, the agent hears ringback and stays mute
  until the callee greets.
  Do not set answerOnBridge: the SIP To is already answered so the
  agent can retrieve the task file; answerOnBridge only applies to
  an unanswered inbound leg and has been seen to skip the PSTN Dial
  after a SIP first hop.

  Recording is call-level on the create request (Record=true,
  RecordingChannels=dual). Do not put record on <Dial>.

  Do not set MachineDetection / AsyncAmd on this call. They would classify
  the To leg (the xAI agent), which is useless. Voicemail is conversational.
