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

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

​
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
Questions Field: The questions array content will vary for each client as the data is pulled from your custom Insights configuration. However, the structure always remains the same: an array of objects with key and value properties.
