如何在异步模式下使用Twilio进行调用 - 经典ASP？

Question

通常，当我运行经典ASP脚本拨打电话时，对于200次通话，加载页面大约需要190秒。如何对Twilio进行异步调用，以便我的页面加载更快，而不是等待每次调用Twilio的响应？

我尝试添加CallBackStatus网址，但是，它没有帮助。这是我的代码：

sub CallANumberSpeakAMessage(fromnumber,tonumber,url)

if isnull(fromnumber) or isnull(tonumber) then exit sub
if len(tonumber) < 10 then exit sub

dim baseurl
dim smsurl
dim from
dim recipient
dim body
dim postdata
dim displayreturn

baseUrl = "https://api.twilio.com"
baseUrl = baseUrl & "/2010-04-01/Accounts/" & authSID & "/Calls"

  'Debug
'response.write "BaseURL:" & baseUrl & "<br><br>"

'setup the request and authorization
Set http = Server.CreateObject("MSXML2.ServerXMLHTTP")
http.open "POST", baseUrl, False, authSID, authToken
http.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"

mFromPhone = fromnumber ' the number to call from
mToPhone = tonumber ' the number to dial
url = Url ' URL handler for the call, should return TwiML
callBackUrl = "http://www.abcserver.com/status_callback.asp"

postData = "From=" & Server.URLEncode(mFromPhone)
postData = postData & "&To=" & Server.URLEncode(mToPhone)
postData = postData & "&Url=" & Server.URLEncode(url)
postData = postData & "&Method=GET"
postData = postData & "&StatusCallback=" & Server.URLEncode(callBackUrl)
postData = postData & "&IfMachine=Continue"

http.send postData
Set http = Nothing
end sub

我已经尝试过改变这个＆＃34; http.open＆＃34; POST＆＃34;，baseUrl，False，authSID，authToken＆＃34; to＆＃34; http.open＆＃34; POST＆＃34;，baseUrl，True，authSID，authToken＆＃34;。当ServerXMLHTTP对象进行异步调用时，页面加载速度很快，但是，它并没有真正调用Twilio，也没有真正发生。

非常感谢任何帮助。
