Which boxes are you talking about Kim? I don't see anything mentioning E&M signalling? Of course it may also be a brain fart on my end. ;)

I've asked various VoIP lists, but haven't had any positive responses yet. I see tons of cheap 2-wire to Ethernet/SIP/VoIP interface boxes on the market, and I know that higher-end Cisco routers have 4-wire E&M cards available for VoIP, but has anyone seen a cheap single or dual-port 4-wire E&M to VoIP "ATA" device like the 2-wire ones anywhere? I can think of some REALLY useful purposes for radio linking at sites that have TCP/IP connectivity... but you really need those E&M leads to do any type of PTT/COS signaling. I asked a couple of the ATA manufacturers about it and they said, "Not enough interest, but we'll build 10,000 of them if someone wants that many." Darn... not quite there yet... and I don't want to buy an 4-port card and a full Cisco to do the job... too expensive for the applications I'm thinking about. I also need the box to be "dumber" as I just want it to pass the E&M leads and not try to interpret them as anything. Nate WY0X Yahoo!
