Anyone know why my VOIP DSP says busy when calling ext 592? I sent my DFSYS file to tech support. They loaded it and said it worked fine for them. I reinitialized the system to check default and it worked. So we reloaded our DFSYS back in and still have the same problem. Although Tech support says he DFSYS file works in there system. Any more ideas before I start all over?:(
