New Features
Call Flow Designer Enhancements
Call Flow Designer is a visual call automation tool that leverages native PBX components, such as Business Hours, IVR, Menu, Prompts, and Developer components to help you easily build custom call workflows. In our V23.1 final update, core components have been refined with clearer routing behavior and expanded logic actions. The key enhancements are summarized in the table below.
| Component | Enhancements |
|---|---|
| Prompt | Adds a Text-to-Speech (TTS) timeout destination. If TTS playback or transcription exceeds the configured timeout, the call is automatically routed to the defined timeout destination. |
| User Input | Adds a Text-to-Speech (TTS) timeout destination. If TTS playback or transcription exceeds the configured timeout, the call is automatically routed to the defined timeout destination. |
| Menu | Improves key input collection logic. When the entered digits has a unique match, the call is routed to the corresponding branch immediately without waiting for the key-press timeout. |

Threshold-Based AI Transcription Alerts
AI Transcription capability alerts now support more flexible thresholds. In addition to the previous 90% and 95%, you can now set alerts at 70%, 75%, 80%, 85%, and 100%, sending email notifications before usage reaches its limit.
*AI Transcription includes both Call Transcription (supported on P-Series Cloud and Software Editions) and Voicemail Transcription (supported on P-Series Appliance, Cloud, and Software Editions).
Flexible Archive Storage Methods
PBX now offers flexible remote archive storage options for easier and more organized file management.
- One-time storage tasks: choose to either create a task folder or save directly to a selected path.
- Recurring storage tasks: choose to create a folder for each archive execution, create and reuse a single task folder, or save directly to a selected path.
- Organize files by date: when enabled, files are automatically grouped into subfolders by date within the selected path.
These enhancements give admins greater control over where and how files are stored to the archieve servers, simplifying file organization and improving workflow efficiency.

Additional Optimizations
- SMS Carrier Expansion: SMS integration carrier now supports VoIP.ms and NETPLANET, alongside existing ITSPs such as General, Flowroute, Twilio, Telnyx, Bandwidth, Alhambra IT, Aspsms and more.
