To learn more, you can read [Why migrate to v2?](/docs/voice-2.0/migration.md) or [What's new?](/docs/voice-2.0/whatsnew.md).\n\nThe Voice API works as a big telephony switch. The Voice API handles incoming phone calls (also known as incoming call “legs”), sets up outgoing phone calls (or outgoing call “legs”), and bridges the two. The incoming call leg may come in over a data connection (from a smartphone or web application using the Sinch SDKs) or through a local phone number (from the PSTN network). Similarly, the outgoing call leg can be over data (to another smartphone or web application using the Sinch SDKs) or the PSTN network.","includeFiles":["docs/voice/**/*.md"],"excludeFiles":["docs/voice/index.md"]},{"title":"Voice API v2 (recommended for new builds/preview)","description":"Which Voice API?

From voice-enabling AI agents to allow real-time conversational AI workflows over the phone, to number masking for privacy, automated appointment reminders, and outreach campaigns with answering machine detection, to bridging calls between PSTN and SIP endpoints, the API offers the flexibility and control needed for modern communications. The Sinch Programmable Voice is a cloud-native global voice platform, composed by multiple Inbound and Outbound voice channels. All these channels can be combined using our powerful markup language called SVAML v2, creating a toolbox capable of building almost limitless use cases. Our SVAML uses the concept of commands, and customers can use a combination of our commands to interact with calls in all channels, in order to model from the most basic to highly complex scenarios, required to fulfill their voice calling needs.","includeFiles":["docs/voice-2.0/**/*.md"],"excludeFiles":["docs/voice-2.0/index.md"]},{"title":"Verification API","description":"The Verification API is a platform for phone number verification.
