Resolving Call Log and Call Usage Discrepancies
If you are comparing your call logs (through either your Console logs or the API /Calls List) against your call usage (through either the Console Usage page or the API Usage/Records) there are a number of considerations to keep in mind for a proper comparison.
Match Call Logs with Usage Logs
In order to match call logs with Usage API, keep these points in mind:
- The
countin the usage API is the number of events (# of calls, in this case) - The
usagereturned via the Usage API is the total number of BILLED minutes per call, rounded to duration defined by the pricing model ( minimum and round quantity ) - In the
usageconsole, call usage is displayed separately as "voice minutes" and "client minutes". Since client calls are a separate entity in the usage API definition, you will need to get the usage for calls and client calls separately. - Not all calls listed in call logs are billed. For example, calls with status :
Failed, orBusy, are not billed and the usage API will not add the usage from those calls. - Internally, the date parameter defaults to midnight. When querying the call logs for a month, use
< 1st day of next monthas the end boundary (do not use<= last day of this month).

How to Reconcile Usage and Logs |
|
Duration of Calls |
Measured in minutes |
Measured in seconds |
Round up duration in your call logs to the nearest minute to match the usage logs. |
|
Voice vs. Client Calls |
Client and Voice calls are treated separately |
Client and Voice calls are merged |
Add your voice and client usage minutes together to match the combined logs. |
|
Call Billing Time |
The start date of the call is the date we use to attribute it |
N/A |
If a call begins in one month and ends in another, usage would be attributed to the first month.. |
|
Call Time Zone |
Calls timezone is always in UTC |
Calls will be in UTC or your local time zone |
If your logs are in your local time zone, normalize them to UTC to match usage. |
