We've tried taking phone calls and it just doesn't work. We don't currently have the manpower to answer the phones and even if we did, most questions just work better by e-mail anyway because we often need datalogs and time to mull over factors and conditions, etc...

We do answer e-mail very quickly, though; sometimes we're even answering email at 2AM to keep up. You will get a quick response if you email us your questions.
