    Hello everyone, we recently did a renovation and I'm trying to replace the very old intercom handset with a new one.

    The old handset is a Thorn handset (unknown model):

    The new model is the Cyfral Smart 5P Universal Home Phone 4 Plus N, 4, 5, 6 Wire System.

    I have tried to use Urmet 1130 as a reference for the wire mapping, as this model looks similar in design to the old handset. The result is that all functions are working (ring, open door, speaking and hearing), but the speaking and hearing volume is really low from both ends of the call.

    If someone know how I can adjust the volume? there some sort of place for that, but it does not affect the device or I might be using it wrong.

    Note: this is an apartment building and I can't replace the building old panel.

    Many thanks!
