Hello Jon and Quentin, I am also trying to get caller id working with my tdm30b using Telewest. What does the cidstart=ring switch do. I have been told that my 3 lines are connected to a Nortel DMS 100. Caller id is active. Any other advise would be appreciated.
Update - Now resolved, good old Telewest changed type of caller id from "Name and number" to just "number"
