I am trying to get a Comdial Impact DSU to work with Keyvoice voicemail. The Voicemail is working fine and the Dialogic Card test runs fine. The DSU has ext 38 -41 set to ATI Device. If run the Dialogic PBXpert the wizard fails on the “Auto Line” test under “Dialing” and if I skip that test the DSU Tones fails too. I’m not sure if I have a programming problem or if the Lines coming out of the DSU are bad. Is there a way to check if the lines on the DSU are okay? Any advice would greatly appreciated.
