# Alerts
> Monitor Voice Gateway alerts for account configuration errors, such as expired TTS/STT credentials and webhook failures.
*Alerts* are created when errors happen in your account configuration. For example, your credentials from the speech provider need to be updated.
To view alerts, select **Alerts** in the left-side menu of the Voice Gateway Self-Service Portal.
Note that you can only filter by a maximum of the last 7 days.
## Alert Types
The following types of alerts can appear on the Alerts page.
| Alert Type | Alert Message | What to do? |
