How do i remove dnd on a samsung dcs 408 pabx ?

it is called voice mail but I have not found anything that mentions diverting calls to voice mail on a handset .

HI, the phones which you don't want to ring put into Do Not Disturb, do this by dialing ( with the handset down ) 401 on their return dial 400 to clear DND. I've posted you a video from ://www.abbeytelecom.com there are loads on here which are really helpful.

How to created incomeing n outgoing call

To turn DND (do not disturb) on and off on any Samsung phone systems (inc. Prostar, DCS, OfficeServ) watch this video clip. Or visit http://www.AbbeyTelecom.com for more vids.

All forwarding can be cancelled by dialling 600, (with your handset down) you then need to re-enter a forwarding to transfer calls to your Voice Mail. Please kake a minute to look at the video I have uploaded for you, hopefully this will help you. There are more like this which include Voice Mail admin on YouTube search 'abbeytel'. or visit www.abbeytelecom.com.
I hope that this is of some use to you

You could try adding a phone to the ring group. This clip shows how to do that on a Samsung DCS 408 and other models. There are many more clips at www.AbbeyTelecom.com which you may wish to "bookmark".

Could you repost your question and tell me the type of phone system you have, you say it is a DCS 40 Prostar but I do not recall the 40, only the 408, 612 and 816. also MMC 601 is for station groups and 603 is for trunks. I'll be glad to help if you can clear this up for me. Thanks, .....Mike
