Nonius solution for telephony, based on IP technology, was designed with a focus on hospitality. The core features include PMS integration providing such services as billing, voicemail, wake-up call, room status update (e.g. housekeeping and mini-bar), and activation/deactivation of outbound calls from the room on check-in/check-out. Billing rates can be defined on-demand and detailed reports are available for guest and hotel staff telephone usage. The solution includes an IP Private Branch eXchange (IP-PBX) and hospitality specific telephones. The Nonius telephony solution implements a cost control management interface and allows for the use of cost-effective technologies such as GSM and analog gateways, ISDN lines, PSTN/primary circuits, VoIP and Skype.
