I have a 8x24ds dr3 with a startalk v1.7 card and v2.1 that i cant get to connect to a KSU, but the v1.7 does. I have the startalk linked to a port but there are no features that i cant get to work. When i try to dial the extension I get a fast busy signal with a not in service on the display. I also try to remove the features from the XFTEST function and try to reboot and nothing comes back. Its a used unit off ebay and when i first connected it i was able to login and it was working and now i dont know how to get it back to default specs. there are no features that work so how can i get it back to default and login so i can activate the features, i have experience with the phone systems so if there is extra stuff i need to do please help.
