Seeing some clues in your question, I assume a few things:
(a) Your discussion is technical, and it may have several topics/issues/problems, one after another.
(b) You do this over a phone call.
(c) You're not comfortable with saying complicated sentences in English, especially when you want to make your points clear.
Basically, I assume that you're in my shoes when I started working abroad.
(Yes, I'm a non-native speaker.)
If someone asked me, "Is there any question? Would you like to add anything?" to conclude one of the topics/issues/problems, and I were in your shoes (i.e., (a), (b), and (c) are true), I might reply:
(No.) It's good/okay (now). (Let's move on (to the next topic/issue/problem).)
The parenthesized parts can be omitted. The slashes (i.e., those / signs) indicate possible alternatives. (So, you have about 2*2*2*(1+(1+3)) = 40 alternatives. ;-) I think it's likeliest that I'd reply "It's good now. Let's move on." or maybe "It's good now. Let's move on to the next issue." when I think just move on may not be clear enough, to the listener(s).
This is clear and concise and easy to pronounce, in my opinion.
Hope it can help you a little. :-)
