RedPort Optimizer Voice
Powerful, Affordable, VoIP and Data Satellite Airtime Control



The Optimizer Voice will cease to be sold as of December 18, 2020. We recommend considering the Optimizer Personal or Optimizer Premier as an alternative. We will continue to support existing hardware until December 18, 2022 and RedPort services on the Optimizer Voice through December 18, 2023

Optimizer Voice combines a powerful satellite data router with voice capabilities, including a full PBX, a prepaid VoIP service with PIN codes, and the ability to carry up to four simultaneous calls over most satellite broadband terminals.

More than just a voice device, RedPort Optimizer Voice gives you everything you need to create a local voice and data network with your satellite device.

Manage your usage, protect against accidental airtime usage, accelerate your data speeds, enable email and web compression, track your location via GPS, and provide routing, filtering and security. (Some fees may apply).


Optimizer Voice as Data Router

Optimizer Voice provides unlimited firewall, filtering, routing, and local GPS repeating. It works with RedPort Mail service for premium access to accelerated email and web compression, as well as GPS tracking via RedPort Tracking or any GsatTrack-based service.

Optimizer Voice for VoIP

The voice capabilities of Optimizer Voice allow for unlimited multi-VoIP (unlimited extensions), conversion from VoIP to circuit-switch, and some of the best compression rates on the planet: 15 minutes of talk time per MB. Because of the PIN-code capabilities of the router, PIN-codes can be created for crew, passengers, work teams, and guests for both data or voice calls.
Unlike traditional satellite airtime plans where only one outgoing call can be made at a time, Optimizer Voice allows for 4 simultaneous outgoing calls over most satellite broadband terminals.

Features and Services


VoIP to Circuit Switch

VoIP to Circuit Switch Conversion

The Optimizer Voice includes VoIP to circuit-switch conversion, which means that you can pick up your cellphone and - using the free XGate Phone app - make and receive traditional satellite phone calls with your smartphone, instead of plugging into the satellite terminal itself.

VoIP Service $

RedPort VoIP Service

Using RedPort VoIP service means that you can make VoIP calls over your satellite terminal using some of the most advanced and sophisticated compression rates on the planet. At 15 minutes of talk time per MB of data use and very low termination rates, RedPort VoIP service provides significant discounts over traditional satellite airtime as well as the ability to create and use prepaid VoIP calling cards for crew, work teams, or guests.

Case Study: Inmarsat IsatHub iSavi


When used with an Inmarsat IsatHub terminal like the iSavi, Optimizer Voice is the only way to provide powerful airtime control features, multi-VoIP, and filtering and blocking of unwanted URLs.
When connected to the iSavi, Optimizer Voice allows you to either place standard Inmarsat calls using your smartphone and XGate Phone app, or place up to four simultaneous  VoIP calls for multiple users with the RedPort VoIP service.
When used with RedPort VoIP service, allows for more than 25% reduction in voice airtime rates when compared with traditional IsatHub voice calls.
