&gt;&gt; I know that the newest versions of Windows (SIP) Messenger<br>
&gt;&gt; do not allow connecting to 3rd party servers,<br>
&gt;&gt; so I plan to use the older versions that do allow it.<br><br>You just need to edit a registry setting to enable 3rd Party SIP communication Service in the latest version.<br>
