1 India finds itself in a unique situation (hopefully). It has several
2 telephone line providers, and they are not all using the same CID
3 signalling; and the CID signalling is not like other countries.
5 In order to help those in India quickly find to the CID signalling
6 system that their carrier uses (or range of them), and get the
7 configs right with a minimal amount of experimentation, this file
8 is provided. Not all carriers are covered, and not all mentioned
9 below are complete. Those with updates to this table should post
10 the new information on bug 6683 of the asterisk bug tracker.
13 ---------------------------------------------------------
14 Provider: Bharti (is this BSNL?)
15 Config: cidstart=polarity_in
17 Results: ? (this should work), but needs to be tested?
19 --------------------------------------------------------
26 --------------------------------------------------------
29 Config: cid_start=ring
34 --------------------------------------------------------
36 Provider: MTNL, old BSNL
37 Config: cidsignalling = v23
42 --------------------------------------------------------
44 Provider: MTNL (Delhi)
45 Config: cidsignalling = v23
49 cidstart = polarity_IN
56 --------------------------------------------------------
59 Config: cidsignalling = dtmf

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