Overview

VX is the world’s first VoIP (Voice over IP) talkshow system — a broadcast phone system that’s so powerful it can run all of the on-air phones for your entire plant, but economical enough for stations with just two or three studios. VX connects to traditional POTS and ISDN telephone lines via standard Telco gateways. But it also connects to VoIP-based PBX systems and SIP Trunking services to take advantage of low-cost Internet-delivered phone services.

VX also weds modern networking to the remarkable power of digital signal processing. VX uses Ethernet as its connection backbone, significantly cutting the cost of phone system installation, maintenance and cabling. Ethernet is a powerful, yet simple way to share phone lines among studios and connect system components. This also makes VX naturally scalable, capable of serving even the largest of facilities — while remaining surprisingly cost-effective for even single stations with more modest needs.

VX plugs right into Axia IP-Audio networks, connecting multiple channels of audio and control via a single CAT-5 cable. Don’t have an IP-Audio network yet? No problem; optional VX interfaces break out audio into analog and digital formats, along with GPIO logic commands. And with informative VSet phones, talent finds it easier than ever to take control of their callers, moving and sharing lines between studios at the touch of a button.

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.

Features

Includes support for AES67, giving broadcasters added flexibility of integrating VXs into any AES67 network and compatible SMPTE 2110-30 networks, in addition to Livewire networks.
HTML-5 control via Pathfinder Core PRO.
SIP call-handling throughout—no internal conversion to analog call handling like some other so-called “VoIP” systems.
Works directly with hosted VoIP or PBX services, and in conjunction with a PBX may support POTS, T1/E1, and ISDN BRI for maximum flexibility and cost savings.*
Standards-based SIP interface integrates with all modern VoIP-based PBX systems to allow transfers, line-sharing, caller ID, and common telco services for business and studio phones.
Standard Ethernet backbone provides a common transport path for both studio audio and telecom needs, resulting in cost savings and simplified studio infrastructure. Connection to hundreds of control devices (software or hardware) is possible.
Each call receives a dedicated processing path for unmatched clarity and superior conferencing.
Native Livewire® integration: One connection integrates caller audio, program-on-hold, mix-minus, and logic directly into Axia® AoIP consoles and networks.
Connect VXs to any radio console or other broadcast equipment using available Telos Alliance AES/EBU, Mixed Signal, and GPIO xNodes. Audio interfaces feature 48 kHz sampling rate and studio-grade 24-bit A/D converters with 256x oversampling.
Powerful dynamic line management enables instant reallocation of call-in lines to studios requiring increased capacity.
VSet Call Controllers™ with full-color LCD displays and Telos Status Symbols™ present producers and talent with a rich graphical information display. Each VSet features its own address book and call log.
The “Drop-in" VSet Call Controller™ modules can directly integrate VXs phone control into your mixing consoles.
Clear, clean caller audio from fifth-generation Telos Adaptive Telephony technology, including Digital Dynamic EQ, AGC, adjustable caller ducking, and audio dynamics processing by Omnia®.
Wideband acoustic echo cancellation eliminates open-speaker feedback.
Support for the G.722 codec enables high-fidelity phone calls from iPhone and Android SIP softphones using a SIP server.
XScreen call-screening software from Broadcast Bionics, provided at no cost.

In-depth

Deployments

Broadcasters can deploy VXs on their servers in the rack room, on shared servers in the centralized data center, or in cloud instances. These deployment options deliver the benefits of virtualization, such as easier facility-wide upgrades, cost-efficiency, and automated deployment without site visits. 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.
