All DIDs ringing to attendant console 1

[drew31fan]

Nortel CS1000 rel 3.0 - For an unknown reason all incoming DIDs are suddenly ringing the attendant console instead of their respective phones. The incoming digits match the extensions so there is no IDC table, and no changes have been made to any route. DIDs are coming in on a PRI so I was able to turn on D-channel messaging. My test calls show the last 4 of the DID on the incoming call but the attendant answers every time and every DID. I've checked individual phones for any call forwarding and found none. I have swapped CPUs and INI'd the switch, no difference. The only change that's been made recently was to the system speed call list. The number of entries was reduced from 100 to 11 since the site only had a few programmed. According to the site (a hotel) that's when all the DIDs stopped working but I don't know of any correlation between an SSC and an incoming DID. I expanded the SSC back to 100 entries but it's made no difference. I'm completely out of ideas here, and going to Avaya is out of the question. Anyone have any suggestions?

Whats the LDN0 set to? I would hazard a guess that its the CVNT in RDR_DATA thats putting it to the attendant but we would need to figure out why the DDI is not working. Stick the RDB up on here also

Thanks, you were on the right track. Looked further into this and found that LDN0 was removed as it was previously thought unnecessary...(d'oh!).
Programmed a generic 4-digit ext for LDN0, problem solved.

Yes, the LDN0 needs to have the number of DDI digits that the exchange sends in it, but it doesn't actually have to be part of the DDI range and therefore it can be a dummy number.

In the UK, it only applies to the ISDN 30e or I421 circuits. It's caught many of us out when fault finding!
