Hi Your modem should have CID support to enable this on your modem do the following AT#CID=1 your modem should respond OK If it responds with ERROR then your modem does not support CID. Then you must order the service from your phone company. I chose the delux because I wanted to see the name of the person who was calling as well as the number I am sure it works fine with the number too.. then I open a minicom window and watch the phone.. The info looks like this DATE 0128 TIME 1454 NMBR 1234567890 NAME Last First What I wanted was a program that would watch the line and send the CID information to any of my consoles when ever a call came through. If your modem does not reply to the string above try some of these strings to see if your modem responds.. AT#CID=1 AT+VCID=1 AT#CC1 AT*ID1 AT%CCID=1 AT#CLS=8#CID=1 This last string may be required for some voice modems even if AT#CID=1 gives an OK response. If you are using windows there is a program that I did not like on my Windows XP box that speaks the name and number of the caller as it comes in but it is shareware and I never got it working on my system. http://www.talkingcallerid.com One neat thing I am doing with this is having my modem pick up when I use my mobile to call the line so I can access my box while away from home, and allowing all other calls to pass to voicemail. sincerely, Patrick ----- Patrick Turnage E-mail: pturnage at tampabay.rr.com AOL Instant Messenger: kg4dqk Home Page: http://www.access-connect.com
