Help ! Can't find endpoints.

Question

Hi,all

I create NLB for two Lync F-E servers , then i run this MSPL:

 foreach (dbEndpoint in QueryEndpoints(To,true))
    {
         totalEndpoints = totalEndpoints + 1;
     }         
    if (totalEndpoints == 0)
    {
        userOffline = true;
    }

totalEndpoints  allways is 0 , i have already set second parameter 'true' ,QueryEndpoints(To,true)

Thank you

Answer 1

?

Answer 2

Are you running the MSPL on all the FE servers?  What SIP message are you using to invoke your MSPL app?

Answer 3

Whar are you using for "To" as a parameter to QueryEndpoints?

It should be the RequestTarget.Uri, and I always set the last parameter to false...

Answer 4

Hi ,Competella AB

To = GetUri(sipRequest.To)

Thanks

Answer 5

Hi ,Oscarnew Consulting

yes,i running the MSPL app on all the F-E servers.

and the entire MSPL :

    To = GetUri(sipRequest.To);
     totalEndpoints = 0;
     userAvailable = false;
     userOffline = false;
  
    foreach (dbEndpoint in QueryEndpoints(To,ture))
    {
         totalEndpoints = totalEndpoints + 1;
         publication = QueryCategory(To, 2, "state", dbEndpoint.Instance);
         if (IndexOfString(publication, "3500") >= 0)
         {
               userAvailable = true;
         }
     }         
    if (totalEndpoints == 0)
     {
        userOffline = true;
        Dispatch("OnRequest");
     } 
}
else
{   
    Dispatch("OnResponse");
}]]>
</r:splScript>
</r:applicationManifest>

Answer 6

Btw , The NLB is created used by hardware .

Answer 7

I do it like this in INVITEs:

        queryUri = RequestTarget.Uri;

       // other code, not relevant

        foreach (dbEndpoint in QueryEndpoints(queryUri, false ))
        {
            totalEndpoints = totalEndpoints + 1;
        }

Answer 8

Hi, i cannot understand what " >=0" stand for into " if (IndexOfString(publication, "3500") >= 0) "

I cannot find into MS MDS documentation.

Thanks

Answer 9

That code is checking for the presence <Availability> element to be 3500 which is online and available.  Details of the various values are here:  Introducing Enhanced Presence

Answer 10

Thanks Oscarn for reply.

I know about 3500 and  " Enhanced Presence"'s codes. I was just focused into " >=0" snippet of code. 

So It only means : ok, check if 3500, or whatever, is present and is greater then 0. Right?

Thanks

Answer 11

The code:

IndexOfString(publication, "3500") >= 0

looks at the string"publication" and finds the index/location of the string "3500".  If the index is non-zero then the string contains "3500" and it assigns true to the userAvailable variable.
