3-5 second delay between call answer and TTS start when using AMD asynchronously in outbound calls

beaver — Tue, 03 Feb 2026 16:29:41 GMT

Hi !

I'm experiencing a significant delay when using Answering Machine Detection (AMD) in asynchronous mode for outbound calls.

Setup:

Using AMD with async mode in outbound calls
TTS configured to play after call is answered

Issue: After the call is answered, there's a 3-5 second delay before the TTS starts playing. This creates an awkward silence that negatively impacts the user experience.

Questions:

Is this delay expected behavior when using AMD in async mode?
Are there any configuration options or best practices to reduce this delay?

Any guidance on how to improve the responsiveness would be greatly appreciated.

Thanks in advance!

Hi, thanks for reaching out!

After speaking with a technical resource, the best way to troubleshoot what is happening with this issue is for you to open a support ticket and provide your account details there so that they can investigate further what is happening.

Please let me know if there's anything else I can do for you.
