1. The internet delay
2. SERVER_BILLING_HOLD_TIME_PRECISION param setting
The param in <system management>-<system params>-<SERVER_BILLING_HOLD_TIME_PRECISION>
The value between “1-1000ms”,if you set “1”, the call duration is 1.001s, vos will billing 2s,001s is 1ms; another example, you set “500”, call duration is 1.501s, vos will billing 2s, also show in the cdr
You should confirm the value with your both side(cutomer and verdor)
In the actual operation process, the accuracy of billing, network jitter, and rate error settings may cause some deviations in two VOS platforms. For example, in enterprise traffic, the call duration is generally not long, and the deviation of the billing duration may be amplified due to the special nature of this service. In V2.1.7.00 and later versions of VOS, the function of bilateral reconciliation was introduced. It is used for real-time reconciliation of two VOSs and provides timely warning information so that operators can find errors and correct billing errors in time. Effectively avoid disputes caused by accounting deviations.
This function effectively improves the reconciliation efficiency between customers and suppliers. The two parties only need to manually verify the accounts in the cycle that generated the alarm.
How to config: The two parties VOS must use V2.1.7.00 or higher version, they can enable bilateral reconciliation function. It needs to be enabled bilateral reconciliation function on the respective VOS’s “Mapping gateway/Routing gateway”: “Operation management > Gateway management > Mapping gateway/Routing gateway > Additional settings > Others > Enable bilateral reconciliation”.
At the same time,you can set bilateral reconciliation cycle、bilateral reconciliation deviation upper and lower and so on.VOS will on the basis of the consumption bias of both accounts is automatically detected according to the cycle.when the deviation reaches the set upper limit value,the VOS will alarm and timely remind relevant personnel to manually check the account balance.After the reconciliation function is enabled on both sides,you can set “Routing bilateral reconciliation deviation” or “Mapping bilateral reconciliation deviation”.
PS: You can define the bilateral reconciliation cycle:
<System management> → <System parameter>: Routing gateway bilateral reconciliation period (minutes) 10-10080
Bilateral reconciliation alarm settings,follows:
Upper:when other VOS of the other party is more than 10 than the current VOS account amount,it will alarm.
Lower:when other VOS of the other party is less than 10 than the current VOS account amount,it will alarm.
An alarm is triggered when the bias of both parties is detected within the warning threshold,fllows:
The alarm value is 100,means other VOS of the other party is more than 100 than the current VOS account amount.if the value is -100,means other VOS of the other party is less than 100 than the current VOS account amount.
And you can use bilateral reconciliation button to check the bias.fllows:
