I am working with a G3si V11 and I am wanting to change the greeting on our main line, the 800 number, and the night greeting. We just got rid of our receptionist and moved to the auto attendant. I didn't have a chance to set any of that up but I do get to change it. How do I access it to change the greeting? We have Audix for our voice mail system. Sorry, I'm knew with this.
