Configure Agent for Phone Calls

Once your phone service is created, configure how your agent behaves during phone conversations:

Training Instructions

Specific guidance for phone interactions (e.g., “Keep responses concise for phone calls”)

First Message

Custom greeting message (if not using auto-generation)

Conversation Timeout

Set timeout duration for inactive calls

End Call Training

Instructions for how the agent should end conversations
Best Practices for Phone Agent Training:
  • Keep responses shorter than text-based interactions
  • Include verbal cues and confirmations
  • Train the agent to ask for spelling of names or important details
  • Provide clear next steps at the end of calls
  • Include hold music or transfer instructions if needed

​
Agent Tools for Phone Calls

EndConversation Tool

Agents have access to a special endConversation tool specifically designed for phone interactions.Purpose:
  • Allows agents to proactively end phone calls when appropriate
  • Provides clean closure for support interactions
  • Prevents calls from remaining open unnecessarily
  • Ensures proper conversation lifecycle management
Critical Configuration: Train your agents on when and how to use the endConversation tool for optimal user experience.
When you have fully resolved the caller's question or completed the requested task, 
use the endConversation tool to end the call. Always provide a brief summary 
of what was accomplished and any next steps before ending the conversation.
Use the endConversation tool when:
  • Support issue has been fully resolved
  • Caller’s question has been completely answered
  • Required information has been collected
  • Follow-up actions have been clearly communicated
  • Caller confirms satisfaction with the resolution

​
Supported Languages

Agent Phone Integration supports multiple languages for enhanced accessibility. By default, phone services operate in English, but you can enable additional language support in the Advanced Options during phone service configuration.
English is always available and doesn’t require enabling “Expand Languages”. Additional languages require toggling the “Expand Languages” option in your phone service configuration.

Performance Considerations

Important: Enabling additional languages may impact phone service performance. Only enable multilingual support if your use case specifically requires it.
Best Practices:
  • Use single language mode when possible for optimal performance
  • Test thoroughly when enabling multiple languages
  • Monitor call quality and response times after enabling additional languages

​
Managing Phone Services

​
Viewing Active Phone Services

In your App Details under Phone Numbers, you can:
  • View all provisioned phone numbers
  • See which agent is assigned to each number
  • Check the status of each phone service
  • Monitor call activity and logs

​
Editing Phone Services

To modify an existing phone service:
  1. Navigate to App Details → Phone Numbers
  2. Click on the phone number you want to edit
  3. Update configuration settings
  4. Click “Save” to apply changes

Note: Removing a phone number from the platform doesn’t automatically release it from your Twilio account. You’ll need to manage number releases directly in Twilio if desired.

​
Testing Your Phone Integration

​
Testing Call Flow

  1. Make a Test Call: Dial your provisioned phone number
  2. Verify Connection: Ensure the call connects and the agent responds
  3. Test Agent Responses: Interact with the agent to verify it follows training instructions
  4. Check Call Logs: Review call logs in your app to ensure data is captured correctly

​

​
Integration with Workflows

Phone calls can be integrated into your existing workflows:

​
Call Data Capture

When a phone call is received, a record is automatically created in your app with basic call information:
  • Caller phone number
  • Call start time
  • Call duration
  • Agent assigned to the call
The system captures this call metadata automatically - no additional configuration is required.

​
Workflow Triggers

Use the Agent Conversation Ended trigger in your automations to process phone call outcomes: What You Get:
  • Complete call transcript
  • Conversation duration and metadata
  • Agent responses and customer interactions
  • Call outcome and resolution status
Automation Examples:
  • Create support tickets based on call content
  • Send follow-up emails with call summary
  • Route urgent issues to appropriate teams
  • Update CRM systems with conversation details
  • Generate call reports for management
The Agent Conversation Ended trigger provides the full context of the phone interaction, allowing your automations to take intelligent action based on what was discussed during the call.

​
Viewing Phone Conversations

After a phone call ends, you can view the complete conversation in the record details: Conversation Interface:
  • Navigate to the automatically created record for the phone call
  • Access the Chat/Conversation interface in the record details
  • View the conversation marked as a Voice conversation type
  • Review the complete transcript of the agent-customer interaction
  • See timestamps, agent responses, and customer inputs
This provides full visibility into phone interactions alongside other communication channels in a unified interface.

​
Call Analytics

Create custom analytics and metrics using automations triggered by Agent Conversation Ended: Metrics You Can Build:
  • Call Volume Tracking: Count daily/weekly/monthly call volumes by creating records for each completed call
