Yealink VCM38 Administrator's Guide

| Device Type Licenses and Multipoint Licenses | 57
Licenses
The devices licenses can be divided into the following:
• License for switching a demo machine to a normal machine: if your system is a demo machine, namely
it is used by agents to demonstrate the features to the customers. The monitor will prompt “DEMO
ONLY, NOT FOR RESELL”. A demo machine supports 24-way calls (1 conference creator and 24
participants) and is valid for one year. You can change the demo machine to be a normal machine by
importing a device type license, which you can get from Yealink technical support. After changing to a
normal machine, the VCS device supports 1 video call and 5 voice calls (1 conference creator and 6
participants).
• License for switching between system modes: for third generation VCS device running in Yealink Cloud
system, you need to import this license. Therefore, the VCS device has Yealink Cloud and Standard
system modes.
Multipoint Licenses
Only VC880/VC800/PVT980/PVT950 supports multipoint licenses. After the administrator imports the
multipoint licenses to VC880/ VC800/PVT980/PVT950, you can use them to initiate multipoint video
conferences.
