Sinch Voice API: Choosing between v1 and v2
For all new projects, please use Voice API v2. This is especially important for projects involving:
- AI capabilities like Streams and Voice Relay
- Voice campaigns like Batch calling
You should only use the older Voice API v1 if one of the following is a strict requirement:
- The project must be in General Availability (GA).
- The project requires In-App voice or Conferencing (until these features are available in v2).
One popular use case for a Voice solution is to call numbers from a list or a database and qualify leads to see if they want to speak to a sales rep. Using Sinch's Answering Machine Detection service to screen out answering machines and a simple Interactive Voice Response system to connect interested callees to a sales rep, that's never been easier!
