The small IT firm that I work for is looking to lower their cell phone bill by signing up for the group plan with AT&T wireless which allows everyone you list in your group to be a free call. The problem is that you can only have up to 5 numbers that are not AT&T wireless numbers in your group, which is the majority of our call. So what we would like to do is have our phone system route all incoming calls to are cell phones if no one picks up at the office within 3 rings it would also be nice if it would send the caller id info to the cell phone but it is not a big issue if it can not been done. Is this possible with a Meridian M8x24-DS?
