Data khusus aplikasi untuk permintaan ini. Hal ini memungkinkan pengirim dan penerima memperluas protokol media dengan mudah tanpa harus menggunakan namespace baru dengan pesan kustom.
mediaSessionId
(angka atau tidak ditentukan)
ID sesi media tempat permintaan diterapkan.
requestId
angka
Id permintaan, digunakan untuk menghubungkan permintaan/respons.
sequenceNumber
(angka atau tidak ditentukan)
Nomor untuk menyinkronkan semua perintah antrean.
Jika diberikan untuk perintah antrean, SDK akan memverifikasi bahwa nomor urut antrean terbaru cocok dengan permintaan.
SequenceNumber saat ini diberikan sebagai bagian dari antrean keluar pesan
yang diubah.
