You're here long enough to know official answer, there's no voip server package from MikroTik and no support for custom packages or any other way how to install you own stuff.
Other than that, RouterOS has Linux inside, so if you find a way how to put your stuff in, it could work. There were some exploits for older versions, to give you shell access. I don't know if anything still works with current version. But it wouldn't be good solution anyway, you'd have problem with updates, so you'd probably have to keep some old version forever, you'd be on your own with everything, ... so maybe fun thing to play with, but hardly for any serious use.
