Business telephony as part of your IT infrastructure.
JITIS designs availability, endpoints, call flows and secure connectivity together with networks, cloud services and operating workflows.
Communication as part of your business infrastructure
Plan business telephony, reachability and collaboration as one coherent operating environment.

Reachable wherever work happens: in the office, at home or on the move, your business number follows the agreed call flow.
Professional call handling: Use queues, announcements and voice menus instead of leaving callers with a busy signal.
Flexible communication Combine telephony, video meetings and team communication in a system that fits your workflows.

On-premises and hybrid telephony: controlled and expandable
For organisations that need locally operated or hybrid telephony, JITIS compares suitable systems, operating models and integration paths. The selected solution is based on call flows, sites, supportability and existing infrastructure.
Systems for different operating sizes: From AGFEO systems for small and medium-sized businesses to expandable solutions from MITEL oder Innovaphone.
A professional starting point: Professional setups are also possible for demanding home offices and smaller organisations, including architectures based on the familiar AVM Fritz!Box.
Controlled migration: We modernise an existing system or plan a controlled replacement.
More than calls: functions and integrations
Modern communication connects call handling with meeting rooms, door intercoms and business applications where this improves daily workflows.
Call management: Configure queues, interactive voice menus and time-based routing.
Meeting rooms: Equip meeting rooms with cameras, microphones and displays for dependable hybrid meetings.
Door intercom integration: Connect compatible doorbells and video intercoms to phones, computers or mobile devices.
Digital office: Integrate functions such as fax-to-mail, voicemail-to-mail and compatible CRM systems.
