如何在 JsSIP 中处理音频流?
How to handle audio stream in JsSIP?
我正在创建 React 应用程序,它使用 JsSIP 库来接听通过 VoIP SIP 提供商发出的呼叫。
我已经创建了一个有两个按钮(接受和拒绝)的页面。它成功地在 SIP 服务器上注册了 SIP 客户端。它也成功接听电话,我可以接听。但是接听电话时听不到任何声音。
正在注册 JsSIP 客户端(在 willReceiveProps
因为我有 props 更改后的连接信息):
const socketHost = 'wss://' + contactCenter.host + ':' + contactCenter.port
const socket = new JsSIP.WebSocketInterface(socketHost)
const configuration = {
sockets: [socket],
uri: 'sip:' + contactCenter.login + '@' + contactCenter.host,
password: contactCenter.password,
socketHost: socketHost,
}
const coolPhone = new JsSIP.UA(configuration)
coolPhone.on('connected', (e: any) => {
const messages = ServiceContainer.get<MessageManagerInterface>(ServiceTypes.Messages)
messages.addSuccess('SIP connected')
})
coolPhone.on('newRTCSession', (e: any) => {
const messages = ServiceContainer.get<MessageManagerInterface>(ServiceTypes.Messages)
messages.addAlert('New call')
const session = e.session
session.on('failed', this.resetLocalState)
session.on('ended', this.resetLocalState)
const numberRegexp = /\"(\d+)\"/
const fromNumber = (numberRegexp.exec(e.request.headers.From[0].raw))[1]
const toNumber = (numberRegexp.exec(e.request.headers.Contact[0].raw))[1].slice(1)
this.setState({
callReceived: true,
callSession: session,
fromNumber: fromNumber,
toNumber: toNumber,
})
})
coolPhone.start()
处理回答按钮点击的方法:
private answerCall = () => {
const messages = ServiceContainer.get<MessageManagerInterface>(ServiceTypes.Messages)
messages.addSuccess('Call answered')
const callOptions = {
mediaConstraints: {
audio: true, // only audio calls
video: false
},
pcConfig: {
iceServers: [
{ urls: ["stun:stun.l.google.com:19302"] }
],
iceTransportPolicy: "all",
rtcpMuxPolicy: "negotiate"
}
}
this.state.callSession.answer(callOptions)
this.state.callSession.connection.addEventListener('addstream', (event: any) => {
console.log(event)
this.audioElement.srcObject = event.stream
})
this.audioElement.play()
this.setState({
callAnswered: true,
callReceived: false,
})
}
我做错了什么?
我解决了问题。
问题出在 this.audioElement.play()
行的位置。
我将其移至 addstream
事件的回调:
this.state.callSession.connection.addEventListener('addstream', (event: any) => {
console.log(event)
this.audioElement.srcObject = event.stream
this.audioElement.play()
})
现在可以正常使用了。希望你也觉得有用。
您可以使用 react-sip
npm 库来简化 jssip 在 React 应用程序中的使用:
https://www.npmjs.com/package/react-sip
您只需要将您的连接设置作为道具传递给 <SipProvider/>
,它将位于您的 React 树顶部附近的某个位置。
这将允许您执行基本的 start/stop/answer 操作并在上下文中查看您的呼叫状态!
