What's New in XSTIM


Infinity 5000 desktop devices are loaded with E-MetroTel’s XSTIM firmware. XSTIM is smart VoIP technology that allows for signalling communication between the device and the server and provides smart features unavailable with SIP. XSTIM reduces complexity, allows for remote provisioning & support, and survivability with our SRG solution. 

XSTIM also allows you to hotdesk and temporarily move your device programming over to another device when you are working at another location. It allows for a single license to register your Infinity 5000 device and your InfinityOne softclient via hotdesking which is a great cost saver.
