Monitor interior y video teléfono SIP Función de vista previa de video Introducción

Introducción

Descripción general

Este documento describe la función de previsualización de vídeo para monitores interiores y teléfonos SIP con vídeo. La función de previsualización de vídeo permite que el dispositivo llamado muestre el vídeo del llamante antes de responder la llamada. Se utiliza ampliamente en llamadas de porteros electrónicos, permitiendo a los usuarios verificar a los visitantes antes de responder o abrir la puerta.

Modelos aplicables

Todos los monitores interiores y teléfonos con vídeo de nuestra compañía.

Cómo funciona la previsualización de vídeo

Se admiten dos modos de previsualización:

  • Modo Preview 18x: La conexión de vídeo se establece utilizando los datos SDP transportados en la señalización SIP 18x durante el timbre, permitiendo la previsualización de vídeo antes de responder la llamada.

  • Modo Preview 2xx: El primer mensaje 200 OK solo establece el vídeo (sin llamada de audio). Se envía un segundo 200 OK cuando el usuario responde para establecer la llamada full dúplex.
