QueryEndpoints(string,boolean) function

Microsoft Office Live Communications Server 2005 with SP1


The QueryEndpoints function queries the server registrar for the network endpoints associated with a specified user and hostname combination.



  • userAtHost
    A string containing the user and hostname in the format "someone@example.com" for which endpoints will be queried on the SIP registrar.
  • forceDatabaseLookup
    If true, this function always queries the registrar database; otherwise, if endpoint data is available in the internal cache, it uses that data instead. This parameter is optional; if it is not present, the value defaults to false.

Return Values

Returns a collection of one or more RegistrarEndpoint objects that contain the known endpoints associated with the SIP user and hostname. If no endpoints are found on the registrar, this function will return an empty collection.


This function is valid only in the context of a foreach statement. The foreach element variable must be the dbEndpoint built-in variable. The following example illustrates the correct usage of this function.

Example Code

foreach (dbEndpoint in QueryEndpoints("someone@example.com")) {
  // Inside the body of the foreach statement, the 
  // dbEndpoint.fieldName field can be referenced. Outside 
  // of the body of this foreach loop, any reference to the 
  // endpoint variable evaluates to false.
