Hey everyone, I have 4 analog lines so I bought a TDM400p card that I believe is a clone of a Digium card. I've tried everything but I absolutely cannot get the static off my line. I've used a different computer, different ports, they all do it. I bought a SPA-3000 on eBay for fun and connected it and it works perfectly, there's no static at all and the line sounds clear. Here's my question though. I'd need to get 3 more of these and use 4 of them for all 4 of my analog lines. Are there any issues with doing that or problems? All my inbound calls come through VoIP, this is just for 4 outbound calls, then outbound call 5 and up will also use VoIP. I don't see it being an issue aside from having more physical hardware plus the added benefit of the FXS port but just wanted to check to make sure there's no issue with using multiple ones. Thank you!
