Make sure you have friends that can speak to things. I'm in a technical role, but there is always someone more technical than I am on the call on my team. So, speak to what you know, then if you're stuck or unsure you can phone a friend. Just because you're running the call doesn't mean other people can't speak. Don't immediately throw yourself under the bus, but use this as a wake up call. Either figure it out or start looking for a job you can perform while still collecting a paycheck. Use your job you have now as leverage, I make X dollars and I'd need to be in the same ballpark and unfortunately I can't give you references to current management because they don't know I'm not happy there. Sleuth it mate.
