If you want these values to be set every time a contact is created, no matter who is doing it, create a file named zContact.mod in the ...\site\mods\majic folder with the following contents:
MODIFY cnt notify_ws1 ON_NEW DEFAULT 'wrkshft:400002';
MODIFY cnt notify_ws2 ON_NEW DEFAULT 'wrkshft:400002';
MODIFY cnt notify_ws3 ON_NEW DEFAULT 'wrkshft:400002';
MODIFY cnt notify_ws4 ON_NEW DEFAULT 'wrkshft:400002';
MODIFY cnt notify_method1 ON_NEW DEFAULT '1800';
MODIFY cnt notify_method2 ON_NEW DEFAULT '1800';
MODIFY cnt notify_method3 ON_NEW DEFAULT '1800';
MODIFY cnt notify_method4 ON_NEW DEFAULT '1800';
MODIFY cnt access_type ON_NEW DEFAULT '10005';
MODIFY cnt type ON_NEW DEFAULT '2305';
You will need to re-start Service Desk for this to take effect. The filename can be anything as long as it has the .mod extension.
Cheers,
