Datos específicos de la aplicación para esta solicitud. Permite que el remitente y el receptor extiendan con facilidad el protocolo multimedia sin tener que usar un espacio de nombres nuevo con mensajes personalizados.
mediaSessionId
(número o no definido)
Es el ID de la sesión multimedia a la que se aplica la solicitud.
requestId
número
ID de la solicitud, que se usa para correlacionar la solicitud/respuesta.
sequenceNumber
(número o no definido)
Un número para sincronizar todos los comandos de la cola.
Si se proporciona para un comando de cola, el SDK verificará que el número de secuencia
más reciente de la cola coincida con la solicitud.
secuenciaNumber actual se proporciona como parte de los mensajes salientes de cambios
en la cola.
