Hi all have been working on setting this up for a long time. I just upgraded to IVM 4.11 with sht4b/usb with driver 5.0.1.0 . when a call comes in on line 1 IVM detects ring on line 1 and picks up line 1, OGM menu plays and everything is working great. when call comes in on any one of the other 3 line on the box IVM detects the ring on say line 2 but it still picks up line 1 and line 2 continues to ring. the IVM OGM plays on line 1. this is not good! can anyone help?
