ORTC stands for Object-RTC.

ORTC is an initiative involving Google, Microsoft and several other companies with the effort of defining an object-centric API to real time communications.

At its heart, ORTC aims to replace the current SDP interface that is used by WebRTC as the API used by developers.

The problem with SDP stems from the fact that it is hard to parse and work with using Java Script code.
