-
 **Telemost:** только vp8channel стабильно проходит. DataChannel удалён из Telemost. seichannel не поддерживается. videochannel — best effort.
 
 **WBStream:** все транспорты кроме datachannel работают. DataChannel в обычном guest flow без выдавания модератора не работает — WB Stream выдаёт токены с `canPublishData=false`, и DC не маршрутизирует данные.
