Hi, We have an SBS2003 Standard server with an Eicon DIVA BRI (ISDN) card. Both channels are configured to send and receive but we get quite a few errors of this type every day. I have read elsewhere that initialisation strings can help, but I don't know which ones to try - never had this problem with same card under Symantec Winfax. Has anyone else had this problem, and how did they get round it? TIA, Paul
