re: How to deal with a "phone phobia" in the workplace

First, calm down. It's not going to derail your life. Remember that you know more about what your calling for than they do and approach it that way. Remember that ultimately you're trying To help them (improve their products, find better sources, do it cheaper etc.)

Secondly, don't be embarrassed about it. Talk to someone at your work about it. Not even a supervisor, an equal. Hell, tell the janitor about it. Sharing something with someone really does make it easier to carry.

Finally, if you're a religious man, pray about it and say "I'm just here to do your will". That way no matter the outcome of the call you know you did your part.

As an aside, a college buddy of mine used to wear sunglasses in his office when he made cold calls. Made him feel more anonymous and therefore more secure.
