Dave-in-Decatur's link will probably get the job done (I think the codes are pretty much the same in residential service as Verizon Wireless). I did find a different link that has everything to do with call forwarding on our support page. Here's the link: Call Forwarding. I hope that's what you were looking for. Feel free to post any other questions you may have regarding this feature.

Thanks, I have the info now.
