Summary: [patch] Fix for CallerID on Indian PSTN
Description:
The default asterisk does not detect the caller id in India. Its a DTMF
based system here, where the caller id is sent after the first ring (this
as per tests on the second biggest provider Bharti, still go to test with
VSNL, will update about the same).
Using certain minor changes, could get it working in both the modes.
(polarity and ring), though the polarity mode is more of a hack (since we
initialize the state of the channel with AST_STATE_PRERING rather than
AST_STATE_RING and get the digits). Basically we needed to do dtmf
detection which is done only in PRERING state, so either we could
initialize the state with PRERING (wrong way), or do the detection in RING
state (aftert the first ring) as well.
For the polarity mode, chan_zap.c diff is diff.chan_zap.c.polarity.
For the start of caller id on ring, the present chan_zap.c code detects
the caller id only in bell202 mode. After adding the part to do dtmf
detection, this work, though had to make a hack there to make it stop CID
detection when we receive ZT_EVENT_RINGBEGIN (also this event is not
handled in zt_handle_event). attached diff.chan_zap.c.ring is for the same.

Actually my mobile number is 9949875064 but it is displaying 49875064.
I am using Bharati (AIRTEL) service provide line.
And another thing is that it is not displaying STD CODE for incoming
calls.
i have used following configurations.
