• Control Hub lets administrators change the upgrade channel per device or in bulk for up to 1,000 devices, and external administrators cannot modify MPP software channels. in context
• Changing one device's channel installs that channel's software within a few minutes, while bulk channel changes take effect during the regular maintenance window. in context
• Webex Calling upgrade channels apply to all MPP devices, Cisco ATA 191 and 192, and listed Yealink T4x models. in context
• Webex Calling devices have five software upgrade channels: Stable, Preview, Stable Delay, Beta and Test. in context
• The Preview channel installs the upcoming default software two weeks before it reaches the Stable channel. in context
• Stable is the default upgrade channel for all Webex Calling devices and installs the current preferred software. in context
