The base of the system is a 19″ rack format equipment, with 4 digital inputs and 4 outputs, 2 analogue inputs and 2 analogue outputs and 32 IP inputs and outputs DanteTM/AES67 protocol. 4 IP lines for operator telephone. The equipment behaves as a multi-line IP telephone with SIP protocol signalling. Compatible with IP PBX, SIP Trunking and virtual PBX. Supports analogue and ISDN lines through gateways.



For 8 simultaneous VoIP telephone lines (expandable to 16).



For 16 simultaneous VoIP telephone lines.


Control Applications

Systel IP Original 

Consists of a control application on PC and a conventional IP phone. Based on call queuing, usually for radio. Best choice in high productivity environments with distributed functionality in roles such as producers, controllers and presenters.

Systel IP TV

Similar in appearance to the Original, it is multiplex-based, to provide access to intercom systems, or technical outdoor intercommunication facilities, more commonly used for television.


The operating application integrated into the SYSTELSET+ touchscreen phone allows for very flexible operation and avoids the presence of a PC at the controls or in other confined spaces.

Technical Details

General Features


SIP communications protocol: compatible with VoIP trunking, Asterisk, SIP Phones such as Phoenix Pocket or Phoenix Lite, N/ACIP compliant Audiocodecs such as Phoenix Mercury, Phoenix Studio, Phoenix Venus or Phoenix ALIO and POTS, ISDN, E1 and T1 FXO.

Based on non-blocking digital switching matrix, all 16 lines can be simultaneously live participating in a program with no loss of quality.

GPI/Os: 4 GPI/O’s and reference voltage on each DB15 female connector. All functions are replicated over TCP/IP in the control network.
