I want to put ip phone service on the main screen.I don't want the phone users to click the service button to access the service. What i want is to have the services appearing on the screen one at a time. E.g show service number one for 3 sec and move to service number two for 3 sec and iterate through them. I just need the way of pushing the on the default screen. currently there a company logo on the main screen. We're using SIP not call manager.
