# Patch an ongoing call by session ID and call name

Interact with an ongoing call identified by its session and call name by submitting a set of SVAML commands. Use this to force disconnect, play messages, bridge with another call, or perform other call control actions.

Endpoint: PATCH /v2/projects/{projectId}/sessions/{sessionId}/calls/{callName}
Version: 2.0.58
Security: BasicAuth, SinchOAuth2

## Security:

  - `BasicAuth` (unknown)
    http basic

  - `SinchOAuth2` (unknown)
    oauth2

## Path parameters:

  - `projectId` (string, required)
    The ID of the project.

  - `sessionId` (string, required)
    The ID of the session.

  - `callName` (string, required)
    The name of the call leg within the session, as assigned by the `callName` property in the `dial` command.

## Header parameters:

  - `Idempotency-Key` (string)
    Client-generated idempotency key to safely retry requests. The server uses this key to recognize retries of the same request. If a request with the same key is received within 10 minutes, the server returns the cached response from the original request. Using a random UUID (v4) is strongly recommended.

## Request fields (application/json):

  - `commands` (array, required)
    An ordered list of SVAML v2 (Sinch Voice Application Markup Language) commands that describe a call flow. Commands are executed sequentially in the order they are defined.
**Blocking vs. non-blocking:** Some commands block execution until they complete (`pause`, `webhook`, `menu`, `gotoMenu`), while others return immediately and run in parallel (`dial`, `messages`, `amd`, `answer`, `hangup`, `startRecording`, `stopRecording`, `bridgeCall`, `stopMessages`). Each command's description specifies its behavior.
**Nesting scope:** Commands that appear inside event handlers (e.g., `dial.events.onAnswer`, `messages.events.onFinish`) form independent sequences and execute in their own context — they are not continuations of the parent sequence.

  - `commands.command` (string, required)
    Command to run Answering Machine Detection on the call
    Enum: "amd"

  - `commands.events` (object)
    SVAML commands to execute based on the answering machine detection result. These events define different call flows depending on whether a human, machine, beep, or unknown entity answers the call.

  - `commands.command` (string, required)
    Command to initiate a new call
    Enum: "dial"

  - `commands.callName` (string)
    Identifier for this call leg within the session. Must be unique across all active call legs in the session.
Other commands (e.g., `hangup`) can reference this name to target this specific leg.
    Example: outgoing

  - `commands.from` (any)
    Call origin - Phone Number or SIP endpoint

  - `commands.from.type` (string, required)
    Routes the call to a phone number on the Public Switched Telephone Network (PSTN). The number must be in E.164 format.
    Enum: "PHONE"

  - `commands.from.phone` (object, required)

  - `commands.from.phone.number` (string, required)
    E.164 Phone number

  - `commands.from.type` (string, required)
    Indicates the call originated from a SIP (Session Initiation Protocol) endpoint.
    Enum: "SIP"

  - `commands.from.sip` (object, required)

  - `commands.from.sip.endpoint` (string, required)
    SIP URI of the originating endpoint. Both `sip:` (unencrypted) and `sips:` (TLS-encrypted) schemes are supported.

  - `commands.from.sip.displayName` (string)
    Display name presented to the called party as the caller identity. Transmitted as the display name part of the SIP `From` header (for example, `Alice <sip:alice@example.com>`).
    Example: Alice

  - `commands.to` (any, required)
    Call destination - Phone Number or Stream URI

  - `commands.to.type` (string, required)
    Routes the call to a SIP (Session Initiation Protocol) endpoint.
    Enum: "SIP"

  - `commands.to.sip` (object, required)

  - `commands.to.sip.endpoint` (string, required)
    SIP URI of the destination endpoint. Both `sip:` (unencrypted) and `sips:` (TLS-encrypted) schemes are supported.

  - `commands.to.sip.transport` (string)
    Transport protocol to use for the SIP signalling channel.
If omitted, the platform selects a default based on the URI scheme: `UDP` for `sip:` and `TLS` for `sips:`. Setting this explicitly overrides that default — for example, to force `TCP` for a `sip:` URI or to use `TLS` without switching to the `sips:` scheme.
    Enum: "UDP", "TCP", "TLS"

  - `commands.to.sip.callHeaders` (array)
    Custom SIP headers to be sent in the call setup.

  - `commands.to.sip.callHeaders.key` (string, required)
    Name of the SIP header.
    Example: X-Correlation-Id

  - `commands.to.sip.callHeaders.value` (string)
    Value of the SIP header.
    Example: 12345

  - `commands.to.type` (string, required)
    Routes the call to a WebSocket stream endpoint for real-time audio processing.
    Enum: "STREAM"

  - `commands.to.stream` (object, required)

  - `commands.to.stream.endpoint` (string, required)
    WebSocket endpoint that will accept the incoming connection for real-time audio streaming. Must be a valid WebSocket URL using either `ws://` or `wss://` (recommended). The URL must be reachable from the public internet and capable of handling the negotiated stream protocol.
    Example: wss://example.com

  - `commands.to.stream.streamOptions` (object)

  - `commands.to.stream.streamOptions.version` (integer)
    Defines the version of the stream protocol.
    Example: 1

  - `commands.to.stream.streamOptions.codec` (string)
    Defines the audio codec/format used for the stream audio payload.
Currently, only `PCM` is supported (uncompressed raw audio). Use `sampleRate` to configure the sampling rate for the stream.
    Enum: "PCM"

  - `commands.to.stream.streamOptions.sampleRate` (integer)
    Defines the audio sampling rate (Hz) used for the stream.

For calls that traverse the PSTN, audio is typically sampled at 8 kHz, so using a higher value will not improve perceived quality. 
Higher sample rates can be useful for non-PSTN scenarios (for example, SIP/streaming paths), but will increase bandwidth usage and processing load.
    Enum: "8000", "16000", "24000", "44100", "48000", "96000"

  - `commands.to.stream.callHeaders` (array)
    Custom headers to be sent in the call setup.

  - `commands.to.stream.callHeaders.key` (string, required)
    Name of the header.
    Example: headerKey

  - `commands.to.stream.callHeaders.value` (string)
    Value of the header.
    Example: headerValue

  - `commands.to.type` (string, required)
    Connects to the Voice Relay service to enable STT and TTS services...
    Enum: "VOICE_RELAY"

  - `commands.to.voiceRelay` (object, required)

  - `commands.to.voiceRelay.endpoint` (string, required)
    URL to the server that will accept the web-socket request
    Example: wss://acme.com/agent

  - `commands.to.voiceRelay.enableInterruptions` (boolean)
    Allow "barge-in" during text-to-speech (TTS) playback.
When `true`, TTS playback is interrupted as soon as inbound speech is detected, unless the currently playing content is marked as uninterruptible.
When `false`, TTS playback continues uninterrupted, but an interruption signal is still sent over the WebSocket so the client application can choose to stop playback manually if needed.
    Example: true

  - `commands.to.voiceRelay.ttsVoice` (string, required)
    Sinch Voice Name to use for text-to-speech. Each voice is tied to a specific language variant, gender, and pricing model (Free/Standard or Paid/Generative). See [https://developers.sinch.com/docs/voice-2.0/api-reference/text-to-speech-voices#text-to-speech-voices](https://developers.sinch.com/docs/voice-2.0/api-reference/text-to-speech-voices#currently-available-languages) for details

  - `commands.url` (string, required)
    URL of the webhook endpoint to send the mid-call event to.

  - `commands.fallbackUrl` (string)
    Fallback webhook URL used when the primary webhook URL fails.

    Hangup call
    Enum: "hangup"
