PBX New Features

Omnichannel Message API

With the Omnichannel Messaging API, the PBX acts as a unified hub, forwarding session data (ID, sender, receiver, message type, etc.) to third-party platforms. This enables integration with chatbots, AI, and other messging handling systems for sentiment analysis, automated responses, and flexible workflows.

More Natural Text-to-Speech

The P-Series PBX Text-to-Speech feature now leverages the AWS Polly Neural TTS (NTTS) model, delivering more natural, expressive, and human-like voices to custom prompts, recordings, IVR and beyond. This upgrade improves interaction quality, making conversations sound more professional and engaging for end users.

What’s more, TTS variables are now available in the Call Flow Designer, allowing partners and administrators to generate dynamic call flows. For example, creating self-service assistants that provide real-time, context-based responses. This added flexibility enables richer voice services and a more tailored customer experience.

Additional Optimizations

Enhanced TAPI Integration for Click-to-Call: The Linkus PC Client now supports multi-user remote access and automatic reconnection, making it easier and more reliable to place calls directly from Windows-based CRM applications.
Send Calls to Voicemail with One Tap: With Linkus (except for ios), you can send incoming calls straight to voicemail instantly with a single click, very convenient for those moments when you can’t pick up but still want the call handled properly.

Create CDR download tasks based on specific requirements such as time range, object options, communication type, or specific CDR fields.

This streamlines billing, reporting, and usage analysis, giving users greater efficiency and visibility.

PBX API Bulk Access

YCM now supports bulk PBX API access via its API, giving users centralized retrieval of APIs without logging into each system individually. This provides access to key resources such as extensions, extension groups, contacts, call routing, and other core configurations & data, streamlining customized management and integration.

This matters a lot:

Minimize repetitive logins and manual configuration.
Easily connect with your own management systems.
