Same here, been quite some time since I worked indepth with Vodavi. But if I remember right you pull the first call out of Park, press Conf, then hit the DSS button from the 2nd call park button and hit Conf 2x and it should connect you with the other 2.
soooooo;
Park 1 on DSS
Conf
Park 2 on DSS
Conf
