We have a BCM400 in our office that we use for several businesses within our building. A new customer has phone numbers that we are porting over that conflict with our destination codes. My thought was to change the received digits on our system to 10. When I change it from 4 to 10 what is going to be affected? Is it just going to reset the recieved digits part of the programming or is it going to reset all the line programming?
