Check out grandcentral.com. I think they still offer a free account. They were/are in beta then Google bought them. They give you a local phone number and code for your web site that will allow someone to enter their phone number while on that page of your site. They call you to whatever phone you have designated on your settings page - you can use multiple phone numbers - cell, office etc.
One way I use them is to record teleconferences. With their form on my website, I enter the number of the teleconference (on my website page) and click the call button, which causes a call to my office phone. When I get the call (within seconds) I push 4 on the phone to record the call. Then I enter the access code, etc to join the teleconference. Participate in the teleconference for the next hour or so. When I hang up, I can go back to grandcentral, log in and download the mp3 of the recording.
