You may have to dig into the Airport setup then. I wonder if they've always had a strict/moderate NAT at the Xbox but its only problematic w/ a subset of other Xbox users? In my experience, if everyone else has an Open NAT, a single person with restrictive settings can still connect.
But, if the Xbox is showing a Teredo failure, I think that precludes any chat at all, so possibly not.
Is the ISP-provided box a modem or a router? If a router, I'd check that DMZ is enabled and properly aimed at the Airport device next.
The Spectrum box is just a modem- if I wanted to continue to deal with the Apple stuff, I would get a different router and use the Airport Extreme as a WAP, but I want to get them into something better and this is as good a reason as any.
