Like it or not, the headset girl has turned into the universal symbol for "here's how to contact customer support". It's not cool, and it's not creative -- but it's a very effective way to be sure that people (who can't be bothered to read) find your support number. Even more than that, it's a quick way to show that you have phone support, which can boost customer confidence even if the customer doesn't need to use it.
