我创建mspl以将调用重新路由到ucma应用程序端点



以下是我的MSPL代码

< lc：requestFilter methodNames =" INVITE"

strictRoute =" false"

registrarGenerated =" true"

domainSupported =" true" />

< lc：responseFilter reasonCodes =" NONE" />

< lc：proxyByDefault action =" true" />

< lc：scriptOnly />

< lc：splScript><！[CDATA [





fromUri = GetUri（sipRequest.From）;

fromUser = Concatenate（GetUserName（fromUri））;

toUri = GetUri（sipRequest.To）;

toUserAtHost = Concatenate（GetUserName（toUri），" @"，GetHostName（toUri））;



foreach（sessionExpires in GetHeaderValues（" Session-Expires"））{

if（ContainsString（sessionExpires，" refresher"，true））{

Log（ " Debug"，false，" RespondWithRinging：* skipped;这是一个会话刷新邀请）;

return;

}

}



foreach（getAeaderValues中的userAgent（USER-AGENT））{

if（！ContainsString（userAgent，" mediation"） ;，真））{

Log（" Debug"，false，" RespondWithRinging：* skipped;不是中介服务器请求 ）;

返回;

}

}



if（sipRequest& ;& sipRequest.Method ==" INVITE"）



{

ProxyRequest（" sip：lync1.sti.ksac。 [e-mail]; gruu; opaque = srvr：app1：nKftzU4ORVGCO9Nqq3-m3QAA"）;

}

else {

//转发调用UCMA应用程序。

Log（Debugr，1，Forwarded caller to UCMA app：，sipRequest.From）;

回复（ 302，暂时移动，联系=;）

}

我使用电源外壳注册我的MSPl

New-Csserver应用程序



和我的c＃代码是



私有空运行（）

{

试试

{

_helper = new UCMASampleHelper（）;



_appEndpoint = _helper.CreateAutoProvisionedApplicationEndpoint（）;

_appEndpoint.RegisterForIncomingCall< AudioVideoCall>（AudioVideoCall_Received）;



void AudioVideoCall_Received（对象发送者，CallReceivedEventArgs< AudioVideoCall> e）

{

尝试

{

string _originalRecipientUri = e.RequestData.ToHeader.Uri;







_inboundAVCall.StateChanged + = new EventHandler< CallStateChangedEventArgs>（_ inboundAVCall_StateChanged）;

_inboundAVCall.AudioVideoFlowConfigurationRequested + = new EventHandler< AudioVideoFlowConfigurationRequestedEventArgs>（_ inboundAVCall_AudioVideoFlowConfigurationRequested）;



Console.WriteLine（" Call Received！"）;



_inboundAVCall.BeginAccept（BeginAcceptCB，_inboundAVCall）;



}}



当我接到电话时，MSPL将呼叫路由到UCMA应用程序并转移到代理，但是当代理接受呼叫时，它没有建立，我得到以下错误在ocs logger中找到

可以任何人请帮助我



谢谢。

I create the mspl to transfer reroute the calls to ucma application endpoint

Below is my code for MSPL

<?xml version="1.0" ?>
<lc:applicationManifest
appUri="http://"Domain NAme"/AltRGS"
xmlns:lc="http://schemas.microsoft.com/lcs/2006/05">
<lc:allowRegistrationBeforeUserServices action="true" />
<lc:requestFilter methodNames="INVITE"
strictRoute="false"
registrarGenerated="true"
domainSupported="true" />
<lc:responseFilter reasonCodes="NONE" />
<lc:proxyByDefault action="true" />
<lc:scriptOnly />
<lc:splScript><![CDATA[


fromUri = GetUri( sipRequest.From );
fromUser = Concatenate( GetUserName( fromUri ) );
toUri = GetUri( sipRequest.To );
toUserAtHost = Concatenate( GetUserName( toUri ), "@", GetHostName( toUri ) );

foreach ( sessionExpires in GetHeaderValues( "Session-Expires" ) ) {
if ( ContainsString( sessionExpires, "refresher", true ) ) {
Log( "Debug", false, "RespondWithRinging: * skipped; This is a session refreshing invite" );
return;
}
}

foreach ( userAgent in GetHeaderValues( "USER-AGENT" ) ) {
if ( ! ContainsString( userAgent, "mediation", true ) ) {
Log( "Debug", false, "RespondWithRinging: * skipped; not a mediation server request" );
return;
}
}

if (sipRequest && sipRequest.Method == "INVITE")

{
ProxyRequest("sip:[e-mail];gruu;opaque=srvr:app1:nKftzU4ORVGCO9Nqq3-m3QAA");
}
else {
// Forward the call to the UCMA app.
Log("Debugr", 1, "Forwarded caller to UCMA app: ", sipRequest.From);
Respond("302", "Moved Temporarily", "Contact=");
}

</lc:splScript>

</lc:applicationManifest>

I register my MSPl By Using power shell
New-Csserver application

and my c# code is

private void Run()
{
try
{
_helper = new UCMASampleHelper();

_appEndpoint = _helper.CreateAutoProvisionedApplicationEndpoint();
_appEndpoint.RegisterForIncomingCall<AudioVideoCall>(AudioVideoCall_Received);

void AudioVideoCall_Received(object sender, CallReceivedEventArgs<AudioVideoCall> e)
{
try
{
string _originalRecipientUri = e.RequestData.ToHeader.Uri;



_inboundAVCall.StateChanged += new EventHandler<CallStateChangedEventArgs>(_inboundAVCall_StateChanged);
_inboundAVCall.AudioVideoFlowConfigurationRequested += new EventHandler<AudioVideoFlowConfigurationRequestedEventArgs>(_inboundAVCall_AudioVideoFlowConfigurationRequested);

Console.WriteLine("Call Received!");

_inboundAVCall.BeginAccept(BeginAcceptCB, _inboundAVCall);

}}

When i get the call MSPL route the call to the UCMA application and transfer to the agents but when agent accepts the call it is not establishing and i am gettimg the following error find in ocs logger
