Abstract. In this paper, we develop an epistemic logic for specifying and reasoning about information flow on the underlying communication channels. By combining ideas from Dynamic Epistemic Logic (DEL) and Interpreted Systems (IS), our semantics offers a natural and neat way of modeling multi-agent communication scenarios with different assumptions about the observational power of agents. We relate our logic to the standard DEL and IS approaches and demonstrate its use by studying a telephone call communication scenario.
