VX Enterprise Broadcast VoIP Phone System

VX Enterprise Broadcast VoIP Phone System Features

Includes support for AES67, giving broadcasters added flexibility of integrating VX 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 VX 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 VX 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.

* 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.

VX Enterprise Broadcast VoIP Phone System In Depth

Telos VX Enterprise

With capacity expandable to up to 120 channels (hybrids/faders), Telos VX Enterprise is an appliance-based system ideal for medium to extensive facilities that can grow with your station over time. You can easily expand this modular system and configure it to manage a network of 60 or more studios, each with a dedicated Program-On-Hold input—truly a “whole-plant” solution for on-air phones.

Base system is licensed for up to 24 channels, expand in license increments of 8 up to 120 channels.
Maximum number of SIP numbers: Unlimited
Maximum active on-air calls: 120
Maximum on-air calls on one fader: 12
A Telos system engineering consultation is required for any system configuration over 72 channels.

VX System Components

VX Engine

VX Enterprise and Prime+ are 1RU rack-mount appliances with two Gigabit Ethernet ports and dual-redundant power supplies. VXs is a container-based solution that runs on your own server or in the cloud. VX systems are web-based, so remote control and configuration are easy—engineers can work from any place they can get online.

You’ll notice no audio I/O or telco ports on VX Engines themselves; that’s because all I/O is handled via Ethernet. The AoIP network supports a wide variety of peripherals such as Axia audio consoles, AES67 audio devices, VSet phones, call management software, console-integrated controllers, and more. VoIP services connect through a dedicated WAN Ethernet jack for routing simplicity and easy maintenance.

Dual VX Engines can be configured in a primary/backup scenario for complete redundancy.

VSet Phones

VSet phones can work like a traditional Telos controller, with calls being selected, held, and dropped in the way to which operators have grown accustomed. But because the VX system is so powerful, it unlocks much more functionality: You can spread multiple calls over several faders, transfer calls, switch Shows, enable Auto-Hold, and more.

The LCD delivers detailed line status, caller information, caller ID, time ringing-in or on-hold, and even caller comments entered in screening software applications. Status Symbols help talent run tight, mistake-free shows. Each VSet phone has its own web server for easy remote configuration and software upgrades. A single Ethernet connection supplies IP connectivity and Power over Ethernet.

VSet12

The VSet12 is a 12-line IP-based controller for the VX featuring a display that provides line status and caller information.

VSet6

VSet6 is a 6-line phone controller for VX. With the same capabilities as the VSet12 but half the lines, it’s excellent for smaller or secondary studios.

On-Console Control

Talent can take control of phones without ever having to divert their attention from the board with the Axia Console Controller, which provides the ideal way to integrate broadcast phones into the on-air console—the control center of every studio. VX systems connect directly to Axia Quasar, Fusion, Element, iQx, iQ, and Radius mixing consoles. Use Axia Pathfinder Core PRO to add console control to the iQs virtual console.

You can program the rotary Options Control knobs to trim source or fader gain when turned, and alphanumeric channel displays give complete information on source assignment, channel options, and more.

VSet Call Controller

Want in-console control of your VX system but don’t have an Axia mixing console? No problem—Telos provides VSet Console Controller electronics packages, which may be fitted to your console using panels supplied by your OEM console provider or preferred third-party fabricator.

VSet Desktop Controller

The Telos VSet Desktop Controller with visual line-status indicators provides a simplified hardware interface for operators and talent to manage a fast-paced and error-free talk show. It provides single-press control of up to 12 lines and two channels, freeing users to focus on their content while quickly taking, Drop, Hold, Transfer, and dial calls.

Telos Alliance xNode Audio Interfaces

Telos Alliance xNodes let you connect VX to any non-networked radio console or other broadcast equipment, using standard analog or AES3 I/O. A GPIO xNode provides control logic where needed. The Telos Alliance Mixed Signal xNode provides analog, AES3, and GPIO interfaces to cover all your bases.

Compatible with Call Management Software

Since we introduced the VX product family more than a decade ago, Livewire partners have developed incredible call management software and mobile apps designed specifically to tap into the power of VX VoIP systems. Each of these free and paid software packages has unique features to suit many common workflows, and some include additional features such as prize management and social media integration.

Use with Axia Pathfinder Core PRO

For more custom needs, Axia® Pathfinder™ Core PRO Broadcast Controller and VM can monitor, control, and display all aspects of your VX system. This enables customized solutions such as drag-and-drop construction of custom control panels, 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.
