I am the IT Manager for my company, with a little experience working with telephone systems. We recently added a PRI card to our Vodavi XTS version 2.23-3FE3 telephone system. We also added DID numbers at the same time. Everything seems to be working very good except the Caller ID information is not complete. I am receiving the caller's telephone number and it is being displayed on the LCD screen of each telephone, but the caller's name is NOT being displayed. We have a telephone vendor who has worked on this problem for a couple of weeks, but with no luck. We have contacted the telephone provider (Charter Communications) to ensure they are sending the Caller ID information with each call. They tell us the information is being sent, but we still cannot view the caller's name on the LCD screen. Does anyone have any ideas?? Any help would be appreciated.
