Hi, I am new here and want to try out 3CX because I think that there is much potential in it. I use the 3CX on a LAN with 3 softphones and a Sipura SPA3000 (Linksys). To make connections with the SPA3000 to third parties (voip providers) is not necessary. When I start up 3CX the SPA3000 registers right. The problem is that I lose registration of Line 1 after a couple of minutes. But the SPA3000 continues indicate that is Line 1 is registered. I have placed the configuration screens on the next internetsite: http://home.tiscali.nl/ Can somebody help me ?
