Overview
Radio Over IP Gateways for Analog Radios
The Omnitronics IPR Series of Radio over IP Gateways merge the power and flexibility of IP with analog radio equipment and networks.
This greatly increases communication reach and offers many benefits including interoperability, scalability, low cost of ownership and ease of implementation. It replaces expensive leased lines and is brand independent. The IPR Series enables you to create flexible and powerful radio networks with convenient operator access.

IPR100 RoIP Gateway

The IPR100 RoIP Gateway is designed to provide Voice over IP extensions for analog radio equipment. Each device enables an analog two-way radio to be remotely controlled over an IP link, either in a LAN or WAN environment.

The IPR110+ is a flexible RoIP Gateway that combines VoIP & SIP technologies to enable dynamic connections to remote radios making radio communications more accessible and easy to use.
- Connect disparate radio repeaters via IP
- Integrate dispatch systems to radios via IP
- Interface SIP-based phone networks Directly with radio networks
- Leased Line Replacement

The IPR400 S2 Interoperability Gateway is the big brother to the IPR100 and a fully fledged multichannel RoIP interface combined with an Interoperability Gateway.
It can remotely connect up to four two-way radios over an IP link and allows patching between local radio channels and remote VoIP connections.
The IPR400 S2 is an interoperability power-house that can be used to dynamically patch multiple radios even if the radios are thousands of miles apart.

RoIP Gateways for Secure Communications
Omnitronics RoIP Gateways are not only powerful and easy to install, they also provide security of information.
Save on Cost
Increasing interoperability of a network helps generate gains across productivity, time and other network resources.

Secure Encryption
Flexible
Scaling up has never been so simple: Shake off the limitations of a Telco network with the power of IP!
Omnitronics gateways support multiple protocols. They can be setup anywhere – they’re no longer restricted by a physical cable.
Compatible
Omnitronics RoIP gateways make it so easy to build and manage networks without relying on proprietary Telco equipment..
Reliable
RoIP gateways can build in redundancies and back-up paths – increasing availability and reliability of the network.
