Our sys admin is out on vacation and I've been charged with changing the system greeting for outside callers. I work at a small community college. We have an alternate greeting that we use that gives summers hours and other info. I need to know how to change from the current greeting to the alternate greeting (I'm assuming we saved the one we used last summer). Assume that my knowledge is limited but I do have full access (a dangerous combination).

Just to be clear, this is for all incomming calls, not on an individual ext or phone.

Any help is greatly appreciated. I dont' want to watch while the Registrar has kittens.
