P-Series PBX V23.1 BETA Enhancements

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 V23.1 BETA, 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.
Dial By Number	Introduces explicit Transfer Success and Invalid branches. If the entered number has a unique match, the call proceeds immediately without waiting for the key timeout.
Transfer	Adds IVR as a supported destination. Custom destinations now support feature code configuration, allowing routing via complete feature codes.
Internal Data Ops	Separates *Get / Set* operations from Developer components into a dedicated Internal Data Ops component. Adds more Get options, including system information and system capabilities. Introduces Login Last Queue in Set Agent States.
Email Sender	Extracted as a standalone component in the ToolBox panel. Supports variable input, enabling dynamic email content within call flows.
Database Access	Extracted as a standalone component in the ToolBox panel. Adds a configurable timeout destination.
HTTP	Extracted as a standalone component in the ToolBox panel. Adds a configurable timeout destination.
Others	Adds configurable end keys (0–9 or none). Supports dialing Call Flow numbers directly, enabling blind transfer or presence-based routing to Call Flows.

Refer to the configuration guide for detailed setup instructions, then upgrade your PBX to V23.1 BETA to test these enhancements and create customized call flows. If you encounter new workflow issues or have additional requirements, feel free to share your feedback with us.

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.
