I believe that they were around AUD$2000 per pair for the IPR100. This unit does a number of different PCM compression modes from 8 to 64kbps and regenerates DTMF and PL (CTCSS) tones at the remote end. They can use E&M or voice activity detection or just constant streaming. In my application I used them to remotely connect a marine VHF radio to a Centracom dispatch console via an ITA2000 tone remote adaptor. I was a bit concerned that there may have been a problem with them passing the Motorola TRC tones but that part works perfectly with reliable keying every time. I still have to set up the RX audio levels properly though (which just requires some time...). I figure if they work for the TRC stuff they may also work in a Spectra-Tac or similar voting system. The only thing you'd have to watch in this case is that network latency is kept low with minimal jitter. I wouldn't recommend trying this over a DSL link for example, but on a dedicated network it should work fine. They also support QoS tagging of the IP traffic. BTW, I'm not connected with Omnitronics in any way - just a satisfied customer.
