ask round -to invite?

[FATE91]

Hello.I saw here, on site that ask round means to invite. But does it really mean to invite? And what the difference then with ask over? Besides, I've looked up and found that it means to ask several people a question(ask around or round)
Am I not right?

Both are right

I aksed the Joneses round for dinner on Saturday
I asked round the table for everyone's opinion.
