I have just installed Nortel Telephony Manager 3.0 , when trying to connect to the PBX using overlay passthru I always recieve invalid username/password. I have searched the solution search at Nortel, patched the TM nad tried entering all upper-case as stated in the SS. Has any body had, and resolved this problem? I do connect when "udpating system data", so when the TM directly inputs the username and password it works just fine.
