Good Day All, I hope that I may find someone who has come a cross this issue before: Completed: SIP 2 Server SETUP - Using http://koha.org/documentation/manual/3.0/appendices/sip2-integration sipserver.xml has been changed to include the machine IP, + port 8023 Tested: telnet 10.106.0.93 8023 login: someuser password: somepassword %s Initiating SIP OK. did a command here and it returns 941 which is ok i guess. =================== Problem: 3M SelfCheck System is showing [ Circulation System Operation Failure - Unspecified Error] in RED. We have already done everything, ensure the username/password/ip/ports/configurations all CORRECT and still does not work. We have already done a telnet session [telnet xx.ip.xx.xx 8023] from inside the 3M SelfCheck Machine [Command Line] and it works OK, returning us results and everything. We have attempted to do something like http://lclpioneer.wordpress.com/2011/05/02/getting-a-3m-self-check-to-work-w... but no use, it still does not work. I hope someone has come a cross this issue when working with 3M SelfCheck with KOHA 3.01.00.999 I appreciate all the help I can get, we have been stuck for over a week attempting at resolving this. Thank you all,
