I've been working on setting up a StarTalk system with only 2 extensions & 2 lines, and all is fine except for one annoying point: if one extension is busy (say, ext. 22), and another call comes in for ext. 22, instead of going directly into the VM on ext. 22, the call rings on the other ext., 23. (and vice versa)

When this happens, the display on ext. 23 shows, for example, "LINE 01>FRED" (FRED being the name on ext. 22, where the call should be going into VM).

Any ideas on this?
