With the rollout of RemoteSpark version 1.9.91 we're receiving reports of users having trouble making calls. The most common reason behind this is a version mismatch between the devices.

The simplest way to resolve the issue is to ensure that you've updated the software on both devices (HoloLens and PC) to the latest version of RemoteSpark.
