Do you think recruiting is sales? And would you go from a sales job to a recruiting job?

Had this discussion with some friends the other day. We talked about if recruiting would be considered a sales position. I have a few recruiter friends and the experience to me sounds similar. Both have base + commission or full commission. Both are important to a company. Both have a "product" they must sell to customers. Both have the cold calling/rejection aspect with quota expectations. So the question is do you guys think recruiting is just another sales position? And would you ever go from sales to recruiting or vice versa?
