I'm playing my current game on Roll20, which looks like it works with CoC, but I also found some other VTTs like Foundry or i forget the one they use for the West Marches 3.5e Campaign.
Some are free, some are free for the program,but you gotta buy the rule set, and some aren't that cheap.
Problem is I can only really advise for 5e, I dont know how much support there is for CoC, but I'm sure I saw the rule set available for FoundryVTT ($50). I also know of MapTools, but I have no experience with that, and for that and Foundry, the players have to connect to you like an old fashioned Multiplayer server.
