I have an Option 11C with several lines that play a message when they are answered; i.e., when a caller dials 307-5882, a message plays(that we re-record based on the need), then they are told that they can press "1" to be directed to a certain person. Currently the "1" sends them to DN 5907. I'd like to change that to DN 5870. Can anyone help me with this? Thanks in advance.
