Use existing RPC mechanisms instead of inventing new ones

[juberti]

Trunk creation, call creation, and signaling byways are basically HTTP RPCs, and there are many existing frameworks for doing such things, e.g., https://grpc.io, https://thrift.apache.org/, etc. I'd suggest that we not reinvent this particular wheel.

Agree and gRPC has worked well for me on other stuff. I would likely go that way over thrift.

+1 on gRPC .. I played with it and works neat

I think the IETF would definitely benefit from having a real RPC-over-HTTP mechanism defined (i.e. other than REST)
