The point of a standup is to learn that there is a tricky issue outside of your immediate work area, and to know who's got expertise on it. That way you know who to contact if "outside" becomes "inside". The actual details, you hash out in a separate meeting with just the people involved. "Offline!" is absolutely the right response if a standup starts veering into technical details.
I had one team of 10 that had a problem with our standups extending into half an hour once. We resolved that we'd make the standup one minute shorter each day. After a month and a half, we had it down to a one-minute standup (6 seconds per person). It was still useful, though a bit extreme - I'd target about 5 minutes for a 10-person standup (30 seconds per).
