Telephony and building security touch at every point: the intercom forwards calls to residents' phones, the elevator needs a line, and so does the emergency phone in the garage. Having two different suppliers install them is a guarantee of finger-pointing the day something stops working.
Dièse Intercom takes on the telephony for your building or business alongside your security systems: lines, handsets, IP telephony, and the dedicated lines your emergency devices depend on.
One point of contact for the security, telephony and internet of your building — that is the whole point.

Frequently asked questions
Can you take over an existing phone installation?
Yes, as with our other services: we take over the equipment already in place, regardless of who installed it.
Can the intercom forward calls to a cell phone?
Yes, with modern addressable systems. Because we install both the intercom and the telephony, forwarding is configured and tested end to end.
Do you also handle the building internet?
Yes. Telephony, internet and the wireless network are part of the same offering — see the Internet and wireless network page.
