SYMPTOMS
When you programmatically send a request to a Microsoft Office Live Communications Server 2003 server by using the Session Initiation Protocol (SIP) OPTIONS method, and you direct that request to a registered endpoint, the server returns a &quot;504 - Server Timeout&quot; result.



CAUSE
This problem occurs because Live Communications Server 2003 does not correctly forward the SIP OPTIONS method to the destination endpoint.



RESOLUTION
To resolve this problem, add the OPTIONS method to the Routing.am request filter file. The request is then proxied correctly. To do this, follow these steps:  Open the Routing.am file by using a text editor such as Notepad. By default, this file is located in the following folder:

C:\Program Files\Microsoft LC\Server

  Type OPTIONS in the following portion of XML code that appears in this file; make sure that you separate it from the other method names by using a comma:   Save the changes to the file, and then quit the text editor.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section of this article.
