Hi everyone! I'm a IT administrator trying to teach myself a bit more about phone systems as I constantly am asked about how to administrate certain systems.

Recently one of my clients has decided to go from 9 phone lines down to 4. I called up Comcast and had them remove the excessive lines. My question now is what do I need to do in the phone system in order to make sure that once the lines are disconnected, the system remains uninterrupted?

I have the "Station Guide" for the Vodavi XTSc-IP but I'm not really sure where to go from there. I also have all the appropiate access codes (I think) left to me from the last person who did the administration on the device.

Before the switch, we had 8 regular lines plus 1 dedicated fax line. We have now cut down to 3 lines and 1 fax line. Comcast has told me that the lines will not be disconnected at least for another couple of days, but I want to prepare now for what I need to do to our phone system.

Any help would be appreciated.

Thanks!!
