One More Reason for Your Customers To Choose Digital Phone Service

The IVI6000 solves one of your biggest problems: how to install Digital Phone Service in apartment buildings without losing the intercom connection to the phones.

Standard intercoms are wired so tenants can answer their intercom from any phone in the unit.

But changing over to Digital Phone disables that function and requires the use of just one phone dedicated to the intercom – an inconvenience for the tenant.

How The IVI6000 Works

The IVI6000 Intercom Interface is a tiny, easy-to-install device that switches all phones in the apartment to the intercom and back. Tenants can answer their intercom from the nearest phone, just like before.

And if they're already on the phone, a musical tone will alert them, if they press the # key, the IVI6000 will put their call on hold, switch to the intercom, allow them to speak to their visitor and then switch back automatically when the Intercom releases the line.

In short, the IVI6000 delivers the phone/intercom features your customers are already used to.

Save a considerable amount of time on every installation because access to the telephone room is not required.

Leave the IVI6000 in place and save even more when subsciber move.
