Phone Meeting W/ A Company. Not sure what to do?

[zoobumz]

I have a phone meeting with a company today about an idea I have for them. I don't have a patent for the idea or even started the paper work for it. I contacted them to get the process rolling, while in the mean time I was going to do the patent filing and wait for their response. Well they contacted sooner than I thought and I have a phone meeting now about the idea. I know about a "nondisclosure agreement" but this is over the phone and not in person. How should I handle this situation or should I just wait on the patent papers?

Any help would be great!

Thanks

Might be too late, but I wouldn't disclose anything to a company about an unpatented product without an NDA in place and some agreement regarding future commerical development of the product.  But if you have to have the discussion, be as vague as possible while still conveying enough information to pique the company's interest.
