How can I change the XPhone Connect Administration link in the Server Manager to https?

Open the XPhone Connect Server program directory and locate the file "StartWebAdmin.exe.config". Open it with a text editor and look for the following area:

<setting name="URL" serializeAs="String">.
<value>http://{0}/xphoneconnect/admin</value>
</setting>

Add an "s" after http and save the file.

Now the admin page opens via XPhone Connect Server Manager as https://localhost/xphoneconnect/admin
