Currently there is no RingCentral Plugin in the IGEL App Portal like there is for Zoom & Webex. This is needed to offload the call resources to the local device rather than the utilizing the VM resources to make the call.

“In a typical VDI environment, RingCentral Phone acts as any other application running in a virtual host environment. However, telephony media stream must make several extra network hops to reach the RingCentral data center. If the network infrastructure is inadequate or unstable users may experience degradation in audio quality due to these extra hops.
With the RingCentral Phone Plug-In for VMware we work to establish a direct media channel from the local user machine where the VMware plugin is installed to the RingCentral data center. This allows us to minimize the number of network hops and optimize the delivery of audio between callers.”
a ring central app would be very usefull
