Known limitations

For per-vendor interoperability information, refer here.

Reference ID Description
30078 For meetings where one of the first two participants joins using PSTN, there is an issue where other participants are sometimes unable to share their screen using the StarLeaf app. A fix for this is coming soon.
30089 For meetings where the first two participants have joined using PSTN, there is an issue where other participants who join using the app cannot see any video presence in the call window. A fix for this is coming soon.
30101, 30102, 30104

On StarLeaf for desktop, when you use Share screen on the Today tab to share content into a meeting before anyone has joined, there are some known behaviors that will be fixed in a future release:
– Participants who join afterwards may see the shared content in a small resolution
– The third participant to join the meeting may, in certain circumstances, enter a separate video meeting
– If the fourth participant to join the meeting leaves, it can cause the first and third participants to hang up as well

29549 On Windows devices, if you use an external display with a different DPI to your desktop, and switch between these displays while in a call or meeting, this could sometimes cause StarLeaf to close. StarLeaf are working on a fix for this issue. Using an external display that has the same DPI as your desktop, will not trigger this issue.


StarLeaf Room for Poly version 1.29 requires a minimum PolyOS version of 3.2.2. If you upgrade to StarLeaf Room for Poly 1.30 with a PolyOS version which is too old, the room system may become stuck in a reboot loop until you perform the PolyOS upgrade.

Most systems are set to auto-update the PolyOS version, but others may need to manually upgrade through the Poly webUI.

27853 StarLeaf Room for Poly: In certain circumstances, the room screen’s wallpaper can appear distorted when the room system wakes from sleep mode. Waking up the touchscreen controller by pressing Camera controls or Contacts returns the room wallpaper to normal.


If or when a StarLeaf Huddle is turned off and on again, the MAC address can change to a random address. StarLeaf are working on a fix for this for existing Huddle room systems. Newly purchased Huddle room systems will not experience this issue

27048 StarLeaf green buttons for Microsoft Teams meetings that use Pexip as the Teams gateway provider will not always work with Office 365 ATP Safe Links . A fix for this is coming soon.
12067 In some circumstances, when a Skype for Business client attempts to add video or content into a StarLeaf meeting with no other video participants there can be unexpected call failure.
11755 There is a BFCP interoperability issue between Cisco VCS and the StarLeaf Cloud which can cause screen share to be disabled mid call.
10858 Internet Explorer 11: When you access a user page on the Portal using Internet Explorer 11, the time zone selection box automatically opens.
