I appreciate everyones help. The card that I purchased was a 9910-410-000. All the other cards are 9910-110-000. Is the 410 card the right one and if it is, does it need to go into a specific slot. Also I know that all programming is done at the console, which programs do I need to go into to activate this card. The customer wants only one multiline phone to work in the managers office. Currently there is a single line phone. Also I noticed on the analog phones that the flash does not work. Is this option 181 and 182. Thanks. If you would like to e-mail me at bilpc2@insight.rr.com or call at 614.554.1596 it would be okay.
