asterisk users - May 2011 - dtmf Caller-id detection before first ring

Hi dears,

I am from saudi arabia and using asterisk 1.6.2.13,Dahdi-2.3.0 and
Digium, Inc. Wildcard AEX800 8-port analog card (PCI-Express) .

I am facing problem with detecting caller id before first ring.I
recorded the dahdi channel using dahdi_monitor command. Where I am
able to see and hear caller-id dtmf tones.

Pl tell me the procedure to upload recorded file if you needed.
Something I want to dig it and make it work in asterisk.

Thanks & Regards,
     Ashik

you have to do these:

1-find suitable patch for your driver(wctdm.c) where the cidbeforering will
be defined.
2-modify the chan_dahdi.c in asterisk, change res to 4000 or higher
3-recompile your driver and asterisk
4-set  cidbeforering=1 and cidstart, .... in the config of dahdi.
5-restart your machine.

for hearing the callerid before first ring use some sound editor for example
waveditor, to see what you hear.
best

Is there a polarity reversal before the caller ID string is sent?
