and troubleshooting.

## Call Log Filters

Various filters are available to help you locate the exact call logs.

| **Filter Name** | **Description** |
| --- | --- |
| **Date / Time Start (UTC)** | Filter logs for specific time ranges: `Today`, `This week`, `This month`, `Previous month`, or `Custom Range`. |
| **Source** | Filter logs by specific source numbers using `Equals` or `Contains`. |
| **Destination DID** | Filter logs by specific DID numbers using `Equals` or `Contains`. |
| **Voice IN Trunk** | Filter logs based on specific Voice IN Trunks. |
| **Trunk Group** | Filter logs based on specific Trunk Groups. |
| **Capacity Group** | Filter logs based on specific Capacity Groups. |
| **Status** | Filter logs by call status: `Any Status`, `Success`, `Capacity Exceeded`, or `Failed`. |
| **Type** | Filter logs by service type: `PSTN`, `Toll-Free`, `Metered Channels`, or `CNAM IN`. |
| **Call ID** | Filter logs by the system-generated Call ID using `Equals` or `Contains`. |

Tip

You can filter multiple values in call log filters, such as source numbers,
destination numbers, or other fields, by entering the values separated by commas
(`,`) or spaces. For example, enter `123,456` or `123 456` to filter
multiple entries in a single field.

Billing Information

Call charges are calculated based on the total call duration, including milliseconds.
Any fraction of time that exceeds a full billing interval is automatically rounded up to the next interval.
This means that even a few milliseconds beyond a complete interval are counted as a full additional interval for billing
purposes.

For example, when the billing increment is `60/60`:

> - If a call lasts `60.000` seconds, it is billed as `60` seconds (one interval).
> - If a call lasts `60.001` seconds (where `0.001` represents milliseconds), it is billed as `120` seconds (two intervals).
