  title: Place and manage a 1-1 VVoIP call (Mavenir BYON)
  version: 1.0.0
  description: >-
    Originate a one-to-one voice/video session on a Mavenir BYON call handling
    deployment, read it back, drive it to Connected, then terminate it. Every
    operationId is verified against
    openapi/mavenir-byon-call-handling-openapi.yml. This workflow cannot be run
    against Mavenir — the spec templates {apiRoot} with a http://localhost:9091
    default, so it must be pointed at an operator's WebRTC Gateway deployment. The
    companion RACM spec is not referenced as a source because it declares no
    operationIds.

  summary: Create a VVoIP session, check it, update its status, and end it.

    Requires a clientId already minted by the RACM registration flow and an HTTP
    Bearer access token from the operator's auth server. transactionId is required
    on every step. clientCorrelator makes step 1 safely retryable.
