Hermes, a versatile and powerful application, relies heavily on its configuration file for its operational parameters. Understanding how to configure Hermes, specifically its Interactive Voice Response (IVR) aspects, is crucial for effective deployment and management. This article delves into the intricacies of Hermes IVR configuration, covering various aspects from locating the YAML configuration file to understanding individual parameters and troubleshooting common issues.
Configure Hermes
The foundation of any Hermes application lies in its configuration. Hermes, by design, searches for its configuration file, written in YAML (YAML Ain't Markup Language), within the current working directory. This means the YAML file must reside in the same directory from where you launch the Hermes application. This seemingly simple detail is often a source of initial confusion for new users. If Hermes fails to start or exhibits unexpected behavior, the first step in troubleshooting is always to verify the location and integrity of the configuration file.
The configuration file's structure is hierarchical, allowing for granular control over various aspects of Hermes' functionality. This includes, but is not limited to:
* IVR Settings: Defining the flow of calls, prompts, and actions within the IVR system. This might involve specifying the greetings, options presented to the caller, and the actions triggered based on caller input.
* Database Connections: Specifying the connection details for databases used by Hermes to store and retrieve data.
* External Service Integrations: Defining the parameters for connecting to external services, such as SMS gateways or CRM systems.
* Logging and Monitoring: Configuring the logging level and destination, allowing for detailed monitoring of Hermes' activities.
* Security Settings: Defining authentication and authorization mechanisms to protect the application.
The flexibility of the YAML format allows for complex configurations to be easily managed and understood. The use of comments within the YAML file is highly recommended to document the purpose of each parameter and improve maintainability.
Configuration
The core of Hermes IVR configuration resides within the YAML file. Let's examine a hypothetical example:
```yaml
# Hermes IVR Configuration File
greeting: "Thank you for calling. Please select an option:"
options:
- number: 1
prompt: "Press 1 for Sales"
action: "transfer_to_sales"
- number: 2
prompt: "Press 2 for Support"
action: "transfer_to_support"
- number: 3
prompt: "Press 3 for Account Information"
action: "account_info"
fallback: "Sorry, invalid option. Please try again."
transfer_to_sales:
destination: "123-456-7890"
transfer_to_support:
destination: "987-654-3210"
account_info:
database: "accounts_db"
query: "SELECT * FROM accounts WHERE account_id = {caller_id}"
database:
accounts_db:
type: "postgresql"
host: "localhost"
port: 5432
user: "dbuser"
password: "dbpassword"
dbname: "accounts"
logging:
level: "INFO"
file: "hermes.log"
