Hi Greg
If the backbone guys are on it then I'm uncertain I can personally add
much. That said however I've assumed the server software load and handset
firmware are all the same. Also reading between the lines are these h323
handsets?
If the local handsets are not registering to the LSP then on the face of it
Id assume they cannot see the local DSP resource. Thats the route Id take.
Id also confirm the station page has the correct location assigned and that
the handset ip-addresses are correctly administered in the ip-network-map.
Also ensure page 3 on the ip-network-region for the LSP is correctly
administered, comparing against a working example. Im sure you have checked
all this, especially if the backbone guys are looking at it.
Im keen to know what the issue is now, keep us posted.
