Developer Response ,

Dear user,

we appreciate your input. We apologize for missing functionality that you have expected inside Integra VoIP app by Freund. Integra VoIP app is designed to be used only with Integra intercoms and Integra SIP Server, therefore most the app functionalities are custom-tailored for our hardware.

We are currently developing a SIP-application of our SIP-servers, having exactly these functionalities you wished for. We also made changes in the description of our app, so it stands more clearly that the app is only to be used with Integra intercoms and SIP servers.
If you would like to take full advantage of this application, we can offer You our product package (Integra SIP Server, Integra Intercom), for more details please contact our sales department: https://freund.ba/en/contactus/

Once again, thank you for your input.
