Intercom Fritz box

[Gast]

Hello,

Does anyone has succesfully installed an analog intercom to the loxone app?
I have tried everything but i can not get it work.
I used the analog to voip spa112
now i am trying to get it work with the fritz box ( i put the fritz box in the network )
setup was to use it as sip server.

I just do not get it to work in the doorcontroller app

does anybody have an idea how to get it to work

thanks
stef
