Publication Date:  2019-07-28 Views:  196 Downloads:  0

Issue Description

Device: IP Pbx U1960 V100R001C01SP100
CDR Server
Outgoing Calls from PRA link get blocked. When some user tries to make the outgoing call through PRA link, system plays an IVR that the "The Bill Pool is Full". 

Alarm Information


Handling Process

 For the immediate solution, login into U1960 and enter the following command 

"config createbill switch off"

after that calls will start to work normally, but to resolve the issue please follow the steps below.Check the U1960 IP at CDR Server.

After you configure the U1960 IP address on the CDR Server, try to ping between each other and then check the state of the CDR Server connection. Login through SSH to the U1960 and enter this commad: "Show billserver state"

if the result is "Connected". It means that 
the connection between the CDRServer and the U1960 came back up.
Run the following command: 
"config createbill switch on"

Root Cause

1. At the beginning the connection between the CDRServer and the U1960 was up and running. The CDR from the U1960 were being retrieved from the billpool.

2. The connection between the CDRServer and the U1960 went down. This caused the billpool to get full. At this point the calls started to fail.


Dont forget to restart the services of CDR server as without that the problem will remain intact.
Please make sure that the connection between CDR server and IP Pbx remain smooth and stable to avoid the issue.
