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.

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.
