Justin Uberti(@juberti):Just promoted our new GPT-Live outbound telephony API to GA, allowing developers to make phone calls from their Live voice agent, via any SIP trunk provider (e.g, Telnyx or Twilio). Calls can use HD Voice and can send and receive keypad events (DTMF). https://t.co/1i5tQiZ4Ac
