Hello there, dear Community!
This post brings you the solution to the issue of U1900 failing to connect to the CDR server. Please see more details below.
ISSUE DESCRIPTION
The unified gateway fails to connect to the CDRServer.
POSSIBLE CAUSES
1. The CDR function is disabled on the unified gateway.
2. The IP address of the CDRServer is incorrectly configured on the unified gateway.
3. The unified gateway and CDRServer are disconnected.
4. Port 2020 is occupied on the host where the CDRServer is deployed.
5. Port 2020 is disabled on the host where the CDRServer is deployed.
SOLUTION
The following assumes that the IP address of the CDRServer is 10.166.42.90.
1. Log in to the U1900 as the admin user and switch to the configuration mode.
2. Run the show createbill switch command to check whether the bill generation function of the U1900 is enabled. nIf the switch is in ON state, the function is enabled. nIf the switch is in OFF state, run the config createbill switch on command.
3. Run the show system information command to check whether the CDRServer IP address configured on the U1900 is correct. Check the BillServer IP Setting parameter. nl If the IP address and port number of the CDRServer are correct, go to Step 4. nl If the IP address or port number is incorrect, run the config system billserver ip 10.166.42.90 command.
4. Run the show billserver state command to check the connection between the U1900 and CDRServer. nl If the CDRServer is in Connected state, the connection is normal. nl If the CDRServer is in Fault state, the connection fails.
5. Check whether port 2020 is occupied. pstop the process that occupies the port and restart the CDRServer.
6. Check whether port 2020 is reachable. Run the ping 10.166.42.90 command on the U1900 to check whether the CDRServer is reachable. Logs in to a server that is in the same network segment as the U1900 and open the command-line interface. Run the telnet 10.166.42.90 2020 command to check whether the connection between the U1900 and port 2020 is disabled by a firewall. If the connection fails, reconfigure the firewall to enable port 2020.
This would be all on solving the issue of U1900 failing to connect to the CDR server.
