Activating OminoPro II Announcement via Helios 2n

[bonster]

Hi,
 
I have a Helios 2n Intercom connected to an OminoPro II and am wanting to know if you can activate an "Announcement" such as "Visitor at Front Door" via the Omni without a SIP server. ?
 
If so, how would you configure both devices for that outcome ?
 
Thanks,
 
Peter

and the answer ended up being no, you need the SIP server to handle the communications from the Helios to the Omni so the announcement can be activated.
