I'm trying to get my Beta line back up. I have everything normal, but it's all hosed. I can call out on the beta line (Linksys), but when I call into it, it rings but not connect; then fast busy after a couple seconds. On the grandstream, I can call out but it won't register at all. Even set at 1 minute. The beta is on jupiter and grandstream is on sip.voipwelcome.com mike...
