Latest reply: Nov 6, 2018 02:59:01 2872 3 12 0

Recently some guys reported similar issue: they can't query call record in BMU. now I share some method to troubleshooting for this issue:

1. check the connection status between BMU and CDR.  You can ping other server from BMU or CDR, check whether there is firewall between these.

2.check the connection status between u1900 and CDR. Login the U1900 by SSH, run command "show billserver state" to check the status, if it is disconnect, check the u1900 and CDR connection configurations, if it is connect, go to next step.

3.check whether the CDR get the call record from U1900. login the CDRServer, query the call record in the CDRServer, if you can't query the record, please check whether the createbill switch is on, you can show createbill switch on U1900. if you can query the record on CDRServer, please go to next step.

4.check the FTP configuration. login the FTP by cmd, show dir to check whether the path is correct.

5.if it still has issue after this, please contact Huawei support team for help.

ok,it‘s very useful,let me do a summarize,there are 4 common reasons that can cause this issue,there are “1:BMU and CDR connection issue”、:2:U19 and CDR connection issue”、“3:CDR can't get the call record from U19”and :4:FTP configurations issue”,if your issue happened while normal running,maybe the 1/2/3 reasons is more possible,you can try it prioritily.
