## Auto-Retry for Failed Calls
Automatically retry calls that fail due to no-answer, busy signals, or errors. Configure retry attempts, delays, and which statuses trigger retries.
**Key features:**
* Up to 3 automatic retry attempts
* Configurable delays between retries
* Works with single calls and batch campaigns
* Webhook notifications include retry status
Learn more in the [auto-retry documentation](/auto-retry).
## IVR Support for Inbound Calls
Bolna now supports IVR (Interactive Voice Response) for Plivo inbound calls. Route callers to different Voice AI agents based on their menu selections.
**Key features:**
* **Menu steps** - Present options and route based on digit pressed
* **Collect steps** - Gather multi-digit input (account numbers, PINs)
* **Multi-agent routing** - Different agent per menu option
* **Conditional branching** - Build complex flows with language selection
* **Context passing** - All collected data sent to agent as context
Configure IVR via the `/inbound/setup` API by adding `ivr_config` to your request. Learn more in the [IVR documentation](/ivr-inbound-calls).
```json theme={"system"}
{
"ivr_config": {
"enabled": true,
"voice": "Polly.Aditi",
"welcome_message": "Welcome to Acme Corp.",
"steps": [
{
"step_id": "department",
"type": "menu",
"prompt": "Press 1 for Sales. Press 2 for Support.",
"field_name": "department",
"options": [
{"digit": "1", "label": "Sales", "agent_id": "sales-agent-id"},
{"digit": "2", "label": "Support", "agent_id": "support-agent-id"}
]
}
]
}
}
```
## Multilingual Message Auto Switching
Bolna now automatically detects the language your users speak and adapts system messages accordingly. Bolna agents analyze conversation patterns and intelligently switche messages to match the detected language.
Bolna agents are now able to identify the dominant language while handling real-world conversational scenarios where users mix languages. This ensures messages are delivered in the language users actually prefer for substantive communication.
**Currently supported message types:**
* **User online check message** - The "are you still there?" prompt when checking if users are on the call
* **Call hangup message** - Closing messages when the agent ends a call
* **Pre-function call message** - Brief wait messages while executing custom tools or API calls
Configure multilingual variants using language codes (e.g., `en`, `hi`, `ta`, etc) and Bolna handles the rest. Learn more in the [language detection documentation](/customizations/auto-switch-multilingual-messages).
## Noise Cancellation During Calls
Bolna now supports noise cancellation during calls, providing clearer audio quality by filtering out background noise for both the agent and the caller.
## Auto Reschedule
Automatically reschedule calls when a user asks to be called at a specific time. The agent will intelligently detect scheduling requests and handle the rescheduling process seamlessly.
