Question

我已经通过cocoapods从https://github.com/chebur/pjsip添加了pjsip lib。

不，我正在尝试使用this pjsip示例连接到sip服务器。

这是我的代码：

func startPjsip() {
    var status: pj_status_t
    // Create pjsua first
    status = pjsua_create()
    if status != Int32(PJ_SUCCESS.rawValue) {
        pjsuaError("Error in pjsua_create()", status: status)
    }
    // Init Pjsua
    var config = pjsua_config()
    pjsua_config_default(&config)
    // on reg state
    config.cb.on_reg_state = { (accountId: pjsua_acc_id) in
        p("on_reg_state", accountId)
    }
    // Init the logging config structure
    var logConfig = pjsua_logging_config()
    pjsua_logging_config_default(&logConfig)
    logConfig.console_level = 4
    // Init the pjsua
    status = pjsua_init(&config, &logConfig, nil)
    if status != Int32(PJ_SUCCESS.rawValue) {
        pjsuaError("Error in pjsua_init()", status: status)
    }
    // Adding UDP transport
    // Init transport config structure
    var udpTransportConfig = pjsua_transport_config()
    pjsua_transport_config_default(&udpTransportConfig)
    udpTransportConfig.port = 5060
    status = pjsua_transport_create(PJSIP_TRANSPORT_UDP, &udpTransportConfig, nil)
    if status != Int32(PJ_SUCCESS.rawValue) {
        pjsuaError("Error in creating UDP transport", status: status)
    }
    // Initialization is done, now start pjsua
    status = pjsua_start()
    if status != Int32(PJ_SUCCESS.rawValue) {
        pjsuaError("Error starting pjsua", status: status)
    }
    // Register the account on local sip server
    var accountConfig = pjsua_acc_config()
    pjsua_acc_config_default(&accountConfig)
    // username
    let username = "10001"
    let domain = "voip01.interpreters.travel"
    let userId = "sip:\(username)@\(domain)"
    accountConfig.id = pj_str_t(ptr: stringToPointer(string: userId), slen: pj_ssize_t(userId.characters.count))
    // uri
    var uri = "sip:\(domain)"
    accountConfig.reg_uri = pj_str_t(ptr: stringToPointer(string: uri), slen: pj_ssize_t(uri.characters.count))
    accountConfig.cred_count = 1
    accountConfig.cred_info.0.realm = pj_str_t(ptr: stringToPointer(string: "*"), slen: pj_ssize_t("*".characters.count))
    let scheme = "digest"
    accountConfig.cred_info.0.scheme = pj_str_t(ptr: stringToPointer(string: scheme), slen: pj_ssize_t(scheme.characters.count))
    accountConfig.cred_info.0.data_type = Int32(PJSIP_CRED_DATA_PLAIN_PASSWD.rawValue)
    let password = "10001"
    accountConfig.cred_info.0.data = pj_str_t(ptr: stringToPointer(string: password), slen: pj_ssize_t(password.characters.count))
    accountConfig.cred_info.0.username = pj_str_t(ptr: stringToPointer(string: username), slen: pj_ssize_t(username.characters.count))

    var accountId = pjsua_acc_id()
    status = pjsua_acc_add(&accountConfig, pj_bool_t(PJ_TRUE.rawValue), &accountId)
    p(accountId)
    if status != Int32(PJ_SUCCESS.rawValue) {
        pjsuaError("Error adding account", status: status)
    }
}

func pjsuaError(_ message: String, status: pj_status_t) {
    let url = NSURL(fileURLWithPath: #file)
    let fileName: String = url.lastPathComponent == nil ? #file : url.lastPathComponent!
    pjsua_perror(fileName, message, status)
    pjsua_destroy()
}

func stringToPointer(string: String) -> UnsafeMutablePointer<Int8> {
    let cs = (string as NSString).utf8String
    return UnsafeMutablePointer<Int8>(mutating: cs!)
}

当我运行应用程序时，我有请求发送到sip服务器，它返回401 Unauthorized (log is here)，根据此doc.，这似乎没问题之后，pjsip发送另一个请求并sip服务器返回403 Forbidden，here is the log。

我已经问过我的服务器人员有什么问题，他说他使用与JsSIP lib相同的凭据用于浏览器客户端，一切正常。 Here is the log他给了我。

我查看了他的日志，看到这些行的不同之处：我的 - 通过：SIP / 2.0 / UDP 他的 - 通过：SIP / 2.0 / WSS

所以我似乎使用了错误的传输协议。但我不知道如何设置pjsip来使用wss协议。

如果您有同样的问题，有人可以帮助我。或者我需要阅读/尝试实现我的目标。

更新

我添加了Starscream，并让它连接到wss：// url。这是代码：

var socket: WebSocket!

override func viewDidLoad() {
    super.viewDidLoad()
    socket = WebSocket(url: URL(string: "wss://voip01.interpreters.travel:4443")!)
    socket.delegate = self
    socket.pongDelegate = self
    socket.headers["Sec-WebSocket-Protocol"] = "sip"
    socket.connect()
}

func websocketDidConnect(socket: WebSocket) {
    print("websocketDidConnect")
    print(socket)
}

它说“websocketDidConnect”。但现在我需要通过此SIP REGISTER传输协议发送wss。我找不到任何有关如何设置pjsip以使用wss的信息。我尝试使用pjsua_transport_create或PJSIP_TRANSPORT_TCP更改TLS，但没有成功。

请有人帮助我找到有关pjsip + websocket支持的信息。
