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).
- command (string**)
| Enum value | Description |
|---|---|
| answer | Indicates that the call is accepted and answered. This enables the binary stream flow. |
| busy | Indicates that the called party was busy. Closes the web-socket connection. |
| reject | Indicates that the call was rejected. Closes the web-socket connection. |
