Complete SIP-server with perpetual license



FREUND INNOVATION CENTER has developed the smart Linux-based IP-INTEGRA SIP-server, which allows our customers to integrate and control IP door phones, IP-telephony & IP-audio solutions with ringbells for schools and institutions & patient call centers.

Additionally, the server also includes a feature so that the customer can integrate the system with nursing and hospital shelters and third party SIP-servers. With our customers in focus, we have also developed the server to enable system customization and OEM development, as well as being able to scale to larger systems with 1024 parallel calls and an infinite number of clients.

The system can also be expanded and adapted to customer needs by purchasing additional features.

IP-INTEGRA SIP-server can be used for offices, private homes, institutions and large residential complexes.
