IP Gateways for Analog Radios

The Omnitronics IPR Series of Radio over IP (RoIP) interfaces are designed to merge the power and flexibility of IP with our customers’ 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.

The IPR100 VoIP (voice over IP) adaptor 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 IPR400 is similar to the IPR100 but  enables up to four two-way radios to be remotely controlled over an IP link. The IPR400 is housed in a compact 1RU 19″ enclosure and provides a superset of the features found in the IPR100 including isolated 4-wire E&M interfaces, multi-casting, voice activity detection, voice compression, CTCSS, SELCAL and DTMF signaling, encryption and RS-232 data tunneling. In addition to these standard features, the IPR400 also provides site monitoring via SNMP and audio bridging (cross-banding). The audio bridging facility further enhances the product’s value at repeater sites by providing the means to link together groups of radios, IP and VoIP channels, in various combinations.

IPR400 S2

The IPR400S2 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.


The IPR110+ carefully combines VoIP & SIP technologies to enable dynamic connections to remote radios making radio communications more accessible and easy to use.  

The IPR110+ is used for two main purposes:
1. Providing radio network coverage to SIP phone users
2. Extending telephone coverage to rugged or difficult locations that are best accessed through wireless communications.

The gateway enables users to connect to remote radio networks from their existing office based SIP compatible PBX systems and, at the same time, it gives users of two-way radios the ability to dial SIP phones or telephone extensions from the field.
The powerful IPR110 Plus builds on the features of the highly regarded IPR100 by providing remote RS-232 channel change and higher levels of security.

The real power of this device comes from the product’s ability to manage connections with SIP phones and SIP compatible PBX systems. This product is perfect for organisations requiring occasional access to a radio network using SIP Phones.
