M3905 Directory - call disconnects

[PhoneK]

We have a M3905 digital phone that all features seem to be working except when they access their directory and try to dial a number. When they do this, it disconnects the call. We have compared the cls to other working phones, replaced the phone (twice), replaced the TN, did a firmware upgrade and still cannot get the directory to dial a number completely. All other phones on that card work fine. Any ideas what might be the issue? I have attached a prt out of the TN.
