Represents SIP server transactions.

The ServerTransactionclass defines a SIP server transaction object located on a SIP proxy or user agent server (UAS).

A ServerTransactioninstance is generated as the ServerTransaction property, available on the RequestReceivedEventArgs object dispatched to a specific method by the MSPL script filter. (For more information, see the Dispatch MSPL built-in function.) There are no public constructors for this class.

The request being serviced by this server transaction can be forwarded by calling CreateBranch () () () () , which will create an associated ClientTransaction . To fork a message, CreateBranchcan be called for each fork. The collection of branches for this server transaction can be obtained as a BranchCollection object by referencing the Branches property. Requests are sent by calling SendRequest(Request) on each branch.

To send a response for the request the server transaction was created to service, call [M:Microsoft.Rtc.Sip.ServerTransaction.SendResponse(Microsoft.Rtc.Sip.Response] with the Response object created by calling CreateResponse(Int32) on the Request object available in the Request property.

The ServerTransactionclass is derived from the Transaction class.
