VMware
Please refer to the VMware Information Guide Timekeeping in VMware Virtual Machines for reference. It should also
be noted that SR140 features which are more real-time in nature, for example G711 Fax or IVR, are more prone to the
impact of these timing inaccuracies.
Supported Host and Client OS:
This SDK is supported for ESXi Server version 4.0.0 or later within the 4.0.x product line using the SR140 with any
client OS supported by both the SR140 and the virtual OS.
