Question

要在拨号方案中处理noanswer通话和播放音频，我们应该：

[default]
exten => _.,1,Progress()
same => n,Playback(filename, noanswer)

但是如果我们使用REST API，文档说：

POST /channels/{channelId}/play

Path parameters
channelId: string - Channel's id
Query parameters
media: string - (required) Media's URI to play.
lang: string - For sounds, selects language for sound.
offsetms: int - Number of media to skip before playing.
skipms: int = 3000 - Number of milliseconds to skip for forward/reverse operations.
playbackId: string - Playback ID.

并且没有选项“noanswer”。

在没有应答频道的情况下，是否有可能从ARI播放音频？
