At Tonmind, we are committed to the continuous enhancement of our IP PA solutions-both in software and hardware. Our latest update to PA System Software for PC-PA System Pro introduces a highly practical and powerful new feature: a built-in SIP Soft Phone. This upgrade further enhances system integration and streamlines communication by eliminating the need for external SIP phone hardware.
What's New: Integrated SIP Phone Functionality
This new addition transforms Tonmind PA System Pro into a fully functional IP softphone, offering seamless SIP communication directly within the software. Fully compatible with Tonmind SIP Speakers, IP Video Intercoms, IP Microphones, Paging Gateways, and ONVIF-enabled Speakers, this feature enables users to handle SIP calls more efficiently than ever before.
1. Built-in SIP Extension for Seamless Communication
Each PA System Pro client now receives an auto-assigned SIP extension number (e.g., 2000, 2001, 2002, etc.). This makes it incredibly easy for external devices or users to call into the system-no additional SIP hardware or manual configuration required.

2. Four Flexible Quick Dial Options
Users can initiate SIP calls in a variety of ways, tailored to different communication needs:
Send messages directly to other SIP extensions
Trigger calls via HTTP URL, enabling easy integration with third-party systems and automation
DTMF tone dialing, ideal for interacting with IVRs or control systems
Manual SIP number dialing, offering a classic and intuitive method
These options empower users with greater control and flexibility, allowing for faster, smarter communication workflows.

3. Multi-Codec Support for Superior Audio
The softphone supports a wide range of audio codecs including Opus, G722, PCMA, and PCMU, ensuring high-definition voice quality across different network environments and use cases.

Why This Matters
The new SIP phone feature transforms Tonmind PA System Pro into a unified communication hub. Users can make and receive SIP calls directly from the software, reducing system complexity and cost by removing the need for separate SIP phones. With automatic number assignment and diverse call initiation methods, the feature is both simple to use and highly adaptable to any project.
Whether you're working on a smart building project, a school broadcast system, or a security integration, this feature enhances both convenience and functionality.
