Chip, I've used eVoice for a while now, and a previous provider for many years before that. I live and work in a large metro area where people can have the same area code, and yet still be a long-distance call via landline. I also have clients from Pennsylvania to Seattle, so it's a courtesy to give them a way to reach me that doesn't incur LD fees. Some of my clients are still very old-school, and would rather chat over the phone than online.
I am encouraging more of my clients to adopt technology such as Skype, but that's not always conducive for the "road warrior"-types who like to call in from their car, between appointments. One of the benefits of using a service like eVoice is being able to forward it to any phone number, anywhere. If I want to forward calls to my VA, associate, or any other number, it's very simple and straightforward.
If you travel, or cover a wide territory, it's a great option to have available for your potential client base.
