Dear Customer,

In January, we released Voice Engine Version 2.0 — a major upgrade from the legacy Version 1.0. To ensure all users benefit from its improved performance, we will be sunsetting Version 1.0 on April 30, 2025. After this time, all existing agents will be automatically migrated to Version 2.0. You can also move the agents on your own to Version 2.0 before this date.

What’s new in Version 2.0:

✅ Advanced background noise & voice cancellation

✅ Adjustable voice speed

✅ Optional background noise

✅ -10% reduction in latency

✅ Enhanced voice recognition with -5% fewer missed words

✅ Smarter voicemail detection

✅ SIP trunking (Enterprise-only)

How to upgrade to Version 2.0: 
For a quick step-by-step guide on how to upgrade your agents, see our documentation.

If you do nothing, all agents will automatically upgrade to Version 2.0 in early May. 

If you have any questions, or trouble please contact us.

Kind Regards,

The Synthflow Team
