Pay for what you need now and scale up any time with additional extensions and plug-and-play handsets. If you need them, you can also add extra applications.

– Secure

NEC Toll Fraud Guard monitors all SIP lines 24/7 against pre-defined tolerances. In the instance of an attack, your admin will be alerted and calls immediately blocked.

– Reporting

Measure and monitor your entire communications. Pre-defined or customised reports in full detail or summary provides you with the information you need.

– Seamless integration

The NEC SL2100 works with normal phone lines, IDSN as well as SIP. A phone system that is ready when you are to make the move to the low cost calling of VoIP.
