innovaphone PhoneLink App not working

Hello. I have installed the PhoneLink app as decribed in the how-to. The only difference was that i had to create the pbx-app-object on my own. It wasn't created automaticly. Version of the innovaphone is 13r2 SR20. When i start the PhoneLink app the first three dots remain red ... only the SRAPS server connection is green. Unfortunately i do not found any more detailed informations of how to cofigure this app. Perhaps somebody can send me some more informations on how to configure the app on my innovaphone pbx.
