# Voice and video names that opened

Study notes. Not vendor documentation and not legal advice.

- Twilio's docs home lists Programmable Voice, Programmable Messaging, Verify, Video, Elastic SIP Trunking, and Conversations among its products.
- The Programmable Voice navigation names outbound calls, incoming calls, gather, conference, IVR phone trees, media streams, and emergency calling.
- Twilio Video's docs opened with quickstarts named for JavaScript, Android, and iOS, and with Video Room concepts.
- Vonage's developer home lists Voice, Video, and Messaging as communication APIs, and the Voice page says text to speech covers over 50+ languages.
- Bandwidth's voice page says you can build a calling application over an HTTPS interface to its voice network.

A web app needs a call and a camera. Write Twilio Programmable Voice plus Twilio Video, or Vonage Voice plus the Video navigation label. Write the TTS line only if you are on the Vonage Voice page.
