I'm thinking, why not add some kind of unit contact clause? After all, if two units from the same faction are sitting next to each other, they can obviously communicate. Thus, when sunspots hit, if you have a unit adjacent to the other faction you're trying to communicate to then that unit can 'run home' (only in the RP sense) and thus communication can continue.
While biased... another suggestion would be for if you have infiltration with a faction you could then communicate but if they don't with you, then you can't talk back...
