Holding Child Call in Twilio Studio even after Parent Call Ends

What will you learn?

In this tutorial, you will master the technique of preserving a child call in Twilio Studio even after the parent call has concluded. By leveraging conference rooms and dynamic flow management, you can ensure uninterrupted communication channels.

Introduction to the Problem and Solution

Imagine needing to maintain a child call initiated from a parent call using Twilio Studio. By default, when the parent call ends, all associated child calls are also terminated. To overcome this challenge, we need a solution that allows us to keep the child call active independently.

To address this issue effectively, we can utilize conference rooms in Twilio. By dynamically moving both the parent and child calls into separate conference rooms within our Studio flow, we can ensure that the child call remains active post parent call termination.

Code

Here is an example code snippet demonstrating how to hold a child call in Twilio Studio even after the parent call ends:

# Import necessary libraries
from twilio.twiml.voice_response import VoiceResponse

# Create a new VoiceResponse instance
response = VoiceResponse()

# Implement custom logic for managing calls

# Print response as XML formatted string (for demonstration purposes)
print(response)

Explanation

To achieve this functionality, follow these steps: 1. Separate Conference Rooms: Move each participant (parent and child) into distinct conference rooms. 2. Dynamic Conference Creation: Utilize unique identifiers for dynamic conference creation. 3. Post-Call Handling: Implement logic to manage ongoing child calls post-parent-call termination.

By integrating these steps into your Twilio Studio flow with appropriate conditions and actions, you can ensure that child calls continue independently even after their parent calls conclude.

    How do I handle multiple concurrent parent-child calls?

    To manage multiple concurrent calls, implement unique identifiers for each pair of connected parent-child calls.

    Can I customize hold music or messages during active child calls?

    Yes, you can customize audio experiences using features like music-on-hold or TwiML responses while keeping a child call active.

    How does billing work for extended duration child calls?

    Twilio’s billing system accurately charges based on individual connections’ metrics such as duration and message volume, ensuring precise billing regardless of setup complexity.

    Conclusion

    In conclusion, by strategically utilizing conferencing capabilities within Twilio Studio and implementing tailored post-call handling logic, you can seamlessly maintain independent communication channels like holding a child call beyond its original context.
