|   | India finds itself in a unique situation (hopefully). 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. Not all carriers are covered, and not all mentioned | ||
|  | below are complete. Those with updates to this table should post | ||
|  | the new information on bug 6683 of the asterisk bug tracker. | ||

|  | Provider: Bharti (is this BSNL?) | ||
|  | Config: cidstart=polarity_in | ||
|  |         cidsignalling=dtmf | ||
|  | Results: ? (this should work), but needs to be tested? | ||

|  | Asterisk still doesn't work with some of the CID scenarios in India. | ||
|  | If you are in India, and not able to make CID work with any of the | ||
|  | permutations of cidsignalling and cidstart, it could be that this | ||
|  | particular situation is not covered by Asterisk. A good course of  | ||
|  | action would be to get in touch with the provider, and find out from | ||
|  | them exactly how their CID signalling works. Describe this to us, | ||
|  | and perhaps someone will be able to extend the code to cover their | ||
|  | signalling. | ||
