It has several +telephone line providers, and they are not all using the same CID +signalling; and the CID signalling is not like other countries. + +In order to help those in India quickly find to the CID signalling +system that their carrier uses (or range of them), and get the +configs right with a minimal amount of experimentation, this file +is provided.
