how does voip work? Unreal BP?

So I ended up taking their platform SDK sample (it's messy and they made widgets with C++ code and such) and recreating the nodes in my project to get VOIP to work.  However, this dude has exposed a bunch of the OVR functions to BP (https://www.unrealengine.com/marketplace/en-US/product/ovr-platform-blueprints) and there's a lot of great stuff in there, including some stuff for VOIP.  The catch is, you need to also get Mordentral's Advanced Sessions Plugin (https://github.com/mordentral/AdvancedSessionsPlugin) so that you can register remote players through BP.  Using these two things together should allow Oculus' VOIP to work with just blueprints.
