I'm trying to add a third node to an existing Stratanet.
Nodes 10 ( DNs 200-264) and 11(DNs 300-331) exist. Created node 12(DNs 600-615).
Added in 102 FLEXIBLE ACCESS CODES 10,11,12 in the other nodes.
Added the remote IPs of the other nodes in 672 IP PRIVATE NETWORK NODE ID ASSIGNMENTS .
Added the 200-264 and 300-331 in
Cannot get an outside line on say node 10 by keying in 109.
Any thoughts on what I've missed?

My guess is something simple that you will say "How do I miss that"

My crystal ball is a bit of a blur so without looking over all 3 systems programming I don't think I could help.

I could bring up the old quote we have used around these part for a long time, "the programming you are trying to do is above user level programming and it my be wise to ask a moderator or admin for detailed support" at a cost I'm sure.
