I have an existing Merlin Legend that I upgraded to a Magix and I purchased a Merlin Messaging card as well as a 100D module. I have never installed a 100D or configured DID but I have the messaging card working great. My circuit from AT&T is ESF/B8ZS WINK on channels 1-12 (my data is on the other channels). AT&T has left me with an IAD that gives me voice on one side and data on the other (my data is working great) When I plug a RJ45 cord from the IAD voice port to the 100D (by the way this is how it was working with my older NEC but I never configured it - it had the cord from the IAD to the T1 Port on the phone system) do I have to configure any channel information? I have (4) pots lines in the system now 801-804 so I assume that I need to put 805-816 in a pool to use? Lastly, AT&T has given me (3) DID numbers over this circuit but I am using 2 digit dial plan. I need (2) of the DID nubmers to go directly to Merlin Messaging without going to operator but how do I do this since the DID will not be used to route to a specific extension (I don't want the DID for routing - just go to the VM). The 3rd DID will be used to go directly to specific extension (the DID number is 233-1555 and I want it to ring on extension 24 and if 24 does not answer it will go to extension 24 mailbox). Any help with this will be greatly appreciated. The DID information in the manual is not very helpful.
