Hi everyone,
I haven't seen this option listed for telephone service, but I have Ooma phone service. It is free, but you must have an internet connection provider. It's an internet phone service. There are paid services available as well, but I use the free service. It includes caller ID and call waiting.
One more thing is that you have to buy the HUB which is the device that makes this service work. I have had it since Dec 2007 and I have no complaints.
You can check it out for yourself to see if this may be an option for you at
www.ooma.com.
