We migrated from an IT 5000 system to an MCD 3300. The old IT 5000 system had an option called "House Phone". If an extension was set to House Phone, that extension could be programmed to auto dial an extension as soon as the handset was lifted. This allowed us to setup a lobby phone to function like an intercom. I've searched the MCD 3300 help to no avail. Does the 3300 have the same ability?
