Qrow: I don't see my sister very often, but she does try to keep in touch... whenever it suits her.

Yang: (shaking her head at the revelation) Wait. You mean you talk to her? That was real?

So, Raven finding him and telling him that message was not the only time they spoke to each other. So, yes, they do talk every once in a while.
