Telos VXs Virtual VoIP System for Radio Overview
Powerful and adaptable Virtual Voice over IP system for broadcast with legendary Telos high-performance audio.
Telos Alliance® introduced broadcasters to the benefits of VoIP a decade ago with VX, the world’s first VoIP talkshow system, in a hardware appliance. Now, Telos VXs is here to help broadcasters reap the benefits of true virtualization as they adapt to changing broadcast workflows and operations, all while making it easier for teams to produce great-sounding and compelling content.
Legendary Telos Audio Quality
Using VoIP, VXs combines modern networking with the power of digital signal processing developed by Telos over the past three decades. Every call gets fifth-generation audio processing packed full of technology engineered to extract the cleanest, clearest caller audio from any phone line—even noisy cellular calls.
VXs includes Smart AGC coupled with our famous three-band adaptive Digital Dynamic EQ, a three-band adaptive spectral processor, and noise gating. Call-ducking and host override are part of the VX toolkit as well. Users can conference multiple lines with superior clarity and fidelity. Send audio gets its own sweetening with an AGC, limiter, and Acoustic Echo Cancellation (AEC) technology that eliminates open-mic feedback.
And if you choose to use compatible telco services, calls from mobile handsets with SIP clients, HD capable telephone sets, and PC apps will benefit from VXs’s native support of the G.722 codec, instantly improving caller speech quality.
Standards-Based for Easy Connectivity
Telos VXs systems are “facility-wide” broadcast phone products. That means multiple studios, multiple stations, multiple shows—with minimal hardware requirements. Telco is delivered via IP from your SIP PBX, hosted VoIP service, or UCaaS provider. For carrier-grade reliability and redundancy, a dedicated SIP trunk circuit can be integrated via a Telos-configured Asterisk-based PBX; legacy circuits such as POTS, ISDN, or T1 can be integrated in the same way. Once connected, all telecom and audio connectivity flows via Ethernet.
New-to-AoIP Installation
Don’t have IP-Audio networking yet? VXs will work with all console brands, networked or not, using Telos Alliance xNodes and the VXs Call Controller drop-in controller for your console. xNodes, like the Telos Alliance Mixed Signal Node, break out audio into analog and digital formats, along with GPIO logic commands. The diagram below shows a typical studio with an analog mixer, using a Telos Alliance Mixed Signal xNode to connect to the console and other broadcast equipment.
AoIP Installation
Installing a VXs VoIP system in facilities already powered by Livewire+™ AES67 networks requires even less time and hardware. Your new VXs phone system will plug right in for seamless integration.
Additionally, support for AES67 gives broadcasters the capability of integrating VXs into any AES67 environment or compatible SMPTE 2110-30 environments. With plug-and-play connectivity, you can network multiple channels of audio with any manufacturer’s AES67- compliant hardware. Support for SAP advertisement means VXs smoothly integrates alongside AES67- enabled Dante® devices.
For those wanting the benefits of a virtual VoIP system but with the simplicity of pre-configured hardware, a single VXs system with up to four channels/hybrids and twelve lines can be pre-installed on the Telos Alliance AP-3000 platform.
Call Management
When combined with call management software, producers and talent can screen and air calls from anywhere with a computer and a solid internet connection. Producers can identify repeat or unwanted callers and enter information about the call, such as topic and mood. This information is available to other production staff and talent in real-time. Various software options are available from Telos Alliance partners.
Use with Axia® Pathfinder™ Core PRO
For more custom needs, Axia® Pathfinder™ Core PRO can monitor, control, and display all aspects of your VXs system. This enables customized solutions such as drag-and-drop construction of custom control panels (pictured), timed Show changes based on studio schedules, or even API translation between third-party systems to display caller information or control lines. The possibilities are endless.

*Due to the wide variation in how traditional phone service can be delivered and the complexities involved in converting those services to SIP, we want to talk with you about your system design before you order. Telos has VX System engineers standing by to help you draw up a configuration that will ensure your VX purchase will perform to your expectations when using legacy telephony circuits.
Telos VXs Virtual VoIP System for Radio In Depth
Deployments
Broadcasters can deploy VXs on their servers in the rack room, on shared servers in the centralized data center, on the Telos Alliance AP-3000 hardware platform, or in cloud instances. Broadcasters can scale VXs in size from a single studio to a facility-wide talkshow system to a multi-location system.
The system is built based on your specific needs by combining features as required: Channels, Lines, and Acoustic Echo Canceller instances. These features combine into a license code, which can be active in one VXs instance at a time.
Features are tiered based on quantity to enable economic growth as overall system size increases. VXs features are available as a subscription, which includes the TelosCare PLUS while the subscription is active. VXs features are also available as a one-time buyout, with the TelosCare PLUS included for the first year and optionally renewable yearly after that.
Pre-Sales Configuration
Pre-sales configuration assistance with a Telos engineer is recommended before order placement. It's free and a great way to ensure the right system components are ordered, with a clear and workable system design. These calls are arranged through your Telos salesperson or dealer and can also include your IT and telecom professionals or vendors.
