Hi Bruce, If you're not hung up on the DECT protocol, why don't you just use a couple of ATAs and WIFI in the middle. ATAs don't need to connect to a PBX, that's just the conventional setup. There's no reason you can't do Phone Set <--> SPA2102 <--> WIFI Bridge <300M of air> WIFI Bridge <--> SPA3102 <--> POTS Line It's the same number of components but if you choose WIFI then you're using commodity hardware and you have lots and lots of choice. I haven't used this exact application but I've used the components separately. For the wifi bridge component, you could use routers in bridge mode or wireless gaming adapters. I've done both. At one of my offices, I used $60 routers running tomato and some big Hawking antennas to connect two buildings across a parking lot. You have total flexibility here, choose your router/bridge, choose your antenna, etc. If it takes multiple hops for some reason, you can buy those range extenders at retail. For the ATA <-> ATA part, I did this for someone who had two warehouses connected by IP but not twisted pair. They wanted to page both warehouses at the same time on their analog paging system. I hooked up the ATAs as shown with one in "Immediate" (Batphone) mode so that as soon as the one paging system went off hook, it took the other end off hook too. It's been a while so I don't recall the config details and I don't think we used SPAs at the time. One nice thing about this is that you could test it end to end on your desk for about $200 and if it doesn't work, the worst thing that happens is that you've got a couple of extra ATAs and routers hanging around. If you want to beef it up, you can go and buy industrial wifi components but at least you'll have proved the concept first.
