Thanks Azro and Tony for the pointers. I decided to give PhonePower a try and see how they do with the 30day guarantee they have.
At the same time, I am taking azro's suggestion and I have set up a toll free gateway using tf.callwithus. I did some math and found that, though I would hit 5000-8000 minutes a month, the majority of that is toll free to conference lines. Without the toll free, I am looking at lower than 300, if my math is correct. So, I went with the low minute, lower prices PhonePower plan for now to see how it is.
My company doesn't reimburse because it's not "required" to have a separate line, but because it is a dedicate office line, it's an instant tax write-off. If within a month, I find that I am not calling much that aren't toll free, and I am far less than the 300 PP has on their cheapest plan, I might go to a pay per call plan, but the fixed price makes it easier for tax purposes and expense management.
And I started really looking at PhonePower after looking through the headache that is LocalPhone's website and plan list. They should really try to find a way to clean that up. As a web developer it gave me a migraine.
Thanks again to everyone in this post that contributed. There is some great info on these forums.
