Transfer Call (Recommended)

SIP REFER Transfer

How it works:

Sends a SIP REFER command to the gateway/trunk
Bot disconnects after successful transfer
Gateway handles the actual call connection

Billing:

Charged only until the transfer completes
No additional charges for transferred portion
Most cost-effective option

Requirements:

Gateway/trunk must support SIP REFER
Proper SIP configuration required

Advantages:

✅ Cost-effective - No charges after transfer
✅ Clean handoff - Bot completely disconnects
✅ Gateway managed - Reliable transfer handling
✅ Scalable - Minimal resource usage

Best for: Standard business transfers, cost-conscious deployments

Bridge Call

Conference Bridge Transfer

How it works:

Creates a conference between lead and transfer destination
Bot remains connected but goes silent
All parties on the same call

Billing:

Full charges for the original lead call
Additional 7¢/minute for the transferred call
Charges continue for entire call duration

Requirements:

No special gateway requirements
Works with any SIP provider

Advantages:

✅ Universal compatibility - Works with any gateway
✅ Reliable connection - No dependency on SIP REFER
✅ Monitoring capability - Bot can monitor the transfer
✅ Fallback option - When SIP REFER isn’t supported

Best for: Gateways without SIP REFER support, monitoring requirements

Choosing the Right Transfer Type

Use Transfer Call When
Use Bridge Call When

Recommended Scenarios:

Your gateway supports SIP REFER
Cost optimization is important
Clean call handoffs are required
High-volume transfer scenarios
Standard business operations

Call Transfer Webhook

Configure real-time conversation data delivery when calls are transferred to human agents, enabling seamless handoffs with full context.

Transfer Webhook Configuration

Provide your webhook URL to receive conversation history and call data immediately when a call is transferred to a human agent.

Enterprise Feature: Call Transfer Webhook enables human agents to receive complete conversation context, improving transfer quality and customer experience.

https://your-domain.com/api/call-transfer

Conversation Format: The conversation array supports multiple formats depending on the AI model used:

Standard: {"role": "user|assistant", "content": "message", "type": "input|response"}
Alternative: {"author": "agent_name", "content": "message"}

Important: The conversation array may have inconsistent keys across different objects, as various AI models generate different data structures. Always validate object keys before processing.

Transfer Webhook Data Fields

Conversation History

Real-time Context:

conversation - Complete conversation transcript up to transfer point
role - Speaker identification (user/assistant)
content - Message content
type - Message type (input/response)

Call Identification

Transfer Context:

call_uuid - Unique call identifier
tenent_id - Organization identifier
phone_number - Customer phone number
user_data - Custom customer data and context

Transfer Webhook Benefits

Agent Preparation
Improved Experience

Informed Handoffs:

Complete conversation history
Customer context and data
Issue identification
Previous interaction summary

Result: Agents start transfers with full context, eliminating customer frustration from repeating information.

Post-Call Insights Webhook

Configure automated post-call data delivery to your systems for analysis and integration.

Webhook Configuration

Simply provide your webhook URL to receive detailed call information immediately after each call completes.

Simple Setup: Just enter your webhook URL - no authentication configuration needed. The webhook will receive unauthenticated POST requests with call data.

https://your-domain.com/api/call-insights
