Ok, here's what I found out from XO. They say that the hunting feature isn't being controlled by them. They say it is the bank that is controlling it. Is it possible for me to set the bank to only accept one call at a time per line? What I mean is, can the second caller on the same number be busied out? If not, they say they can make the changes at the central office but they want me to see if I can do it first.
