A couple of years ago, we discovered that AT&T geoblocks all VOIP traffic from India. We sent some configured phones to them, because the bosses were told by AT&T that it would work fine. Nope. All the tracert results clearly showed them dropping the traffic. But then a few months ago, it started working! The India team emailed me asking to change out the names/extensions, and since then we've had no problems.

@travisdh1 I'm surprised too, but I guess. I think they're probably counting things like rogue USB devices left lying around and such as part of the malicious group.

I think that this decision has to come down to... is this a career change that you want? If this is what you WANT to do, then it is a huge opportunity to build your resume and experience. If this is not something that you want, this could suck big time. it's more about you and your goals than about career options.
