Hello Andreas,

sorry for my late reply, i was off a few days. Your hint was good, the API registration was the problem. I tried to figure out how to register it correctly with success, but with some delay because of the documentaion.

What i did is to create a json api with "com.innovaphone.phoneinfo", register it, and start the api. Like mentioned here https://sdk.innovaphone.com/13r3/sdk/common/lib/appwebsocket.htm i added the apis object and an "com.innovaphone.phoneinfo" object to the msg inside the AppWebsocketAppInfo function, but i'm not sure if i need that.

Tomorrow i will do some more testing, and let you know if i encounter anything.

Thanks a lot and best regards

Mladen
