I have been working in my spare time to get this Telrad Digital400 system up & running at my church. Thanks to you guys that have helped answer my other questions.

I thought it was ready to go, but some testing this afternoon showed up one problem yet.

External calls that are routed to MDN DNs by the auto-attendant (either via single-digit dialing or the caller dialing 1+ ext#) will not forward to voice mail if the extension is not answered. Internal calls to these same extensions forward to voicemail properly. External calls routed to non-MDN DNs also forward to voicemail properly.

Example- The main receptionist has DN 40 as her primary DN. DN 40 also has a flashing appearance on two other receptionist's phones. External calls are properly routed to DN 40 by the auto-attendant, but if DN 40 is not answered, it just continues to ring and never forwards to voice mail. Internal calls to DN 40 forward to voicemail after 4 rings, just like they are supposed to. External calls to non-MDN DNs also work correctly.

This has pretty much halted my progress, as the ability for external callers to leave voicemail messages for all staff members is one of the requirements I was given.

The Digital400 system is running software version 3.05, and IMAGEN is 5.0.
From previous comments that I have received, I gather that 3.05 doesn't support MDNs very well. Is this the cause of my problem? Is 3.05 capable of doing what I am trying to do?

The previous owner had planned to do a software upgrade for the system, but never got around to it. He sent along an extra MPD memory cartridge with DBU5.05C, several EEPROMS for the other boards (ELD, OCD, & COL), and an 11-disk set of floppies with IMAGEN version 5.50E. I hadn't planned to do the upgrade either, using the "if-it-ain't-broke-don't-fix-it" principle, but maybe I need to. Is this a fairly easy task for someone who is experienced working with electronic equipment (electronics tech/engineer for 30 yrs)?

I really appreciate the help the folks in this forum have given to me in getting this system up & running. Hopefully, I'll run out of problems (and questions) soon!
