Telos VX Enterprise VOIP Phone System

* VX is the world’s first VoIP telephone system designed and built specifically for broadcasting.
* Includes support for AES67, giving broadcasters added flexibility of integrating VX Enterprise into any AES67 network, in addition to our own Axia Livewire network.
* Works directly with SIP endpoint telco 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/IP interface integrates with most 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 a simplified studio infrastructure. Connection of up to 100 control devices (software or hardware) is possible.
* Modular, scalable system can be easily expanded and configured to manage a network of 60 or even 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 hybrids, May be expanded in license increments of 8 up to a total of 120 hybrids. A Telos system engineering consultation is required for any system configuration over 72 hybrids.
* Each call receives a dedicated hybrid 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 Enterprise 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.
* Drop-in modules can integrate VX Enterprise phone control directly into your Axia mixing consoles.
* XScreen Lite screening software included.
* Clear, clean caller audio from 5th-generation Telos Adaptive Hybrid technology, including Digital Dynamic EQ, AGC, adjustable caller ducking, and send- and receive-audio dynamics processing by Omnia*.
* Wideband acoustic echo cancellation from Fraunhofer IIS completely eliminates open-speaker feedback.
* Support for G.722 codec enables high-fidelity phone calls from iPhone and Android SIP softphones using an SIP server.
