Skype For Business and ZOOM connectivity

[s.alzaiem]

Hi,

We have recently acquired three Yealink devices (1xVC400 and 2xVC110). The VC400 is in our head office with DIA connection. The VC110 located in our branches with fiber link and DSL consecutively. We also have Skype for Business accounts. We were using ZOOM service as well for sometime.

My question is: How can we connect the yealink devices to Skype for Business in order to allow remote users to join the meeting?
Same question is for ZOOM.

Best Regards,
