Re: [asterisk-users] dtmf Caller-id detection before first ring

2011-05-31 Thread Ashik Ali 
We don't have polarity reversal before first ring I think so. Not confirmed.

 I able to see and hear dtmf and ring tones while playing recorded
wave file using audacity. As per the instruction given by Mr. Pezhman
Lai. I found somthing
while googling . The bug instructions as follows
https://issues.asterisk.org/view.php?id=9096nbn=2.

I am using  8 port digium tdm card. So I decided edit
wctdm24xxp/base.c as per the instruction written in above issue.  As
of now I didn't touch asterisk chan_dahdi.c.

I modified base.c code as follows,

static void wctdm_dtmfcheck_fakepolarity(struct wctdm *wc, int card, u8 sample8)
{
u32 sample16;
struct fxo *const fxo = (wc-mods[card].fxo);

/* only look for sound on the line if dtmf flag is on, it is an fxo
 * card and line is onhook */
if (!dtmf || !(wc-cardflag  (1  card)) ||
(wc-modtype[card] != MOD_TYPE_FXO) || fxo-offhook) {
return;
}

/* don't look for noise if we're already processing it, or there is a
 * ringing tone */
if (!fxo-readcid  !fxo-wasringing  
wc-intcount  fxo-cidtimer + 400) {
sample16 = DAHDI_XLAW(sample8, wc-chans[card]);
if (sample16  2000 || sample16  -2000) {
fxo-readcid = 1;
fxo-cidtimer = wc-intcount;
if (debug  ( card == 2 )) {
printk(KERN_DEBUG DTMF CLIP on
%i %X\n,
   card + 1,sample16);
}
//  dahdi_qevent_lock(wc-chans[card],
//DAHDI_EVENT_POLARITY);
}
} else if (fxo-readcid  wc-intcount  fxo-cidtimer + 2000) {
/* reset flags if it's been a while */
fxo-cidtimer = wc-intcount;
fxo-readcid = 0;
}
}

After compilation of above, I just restarted dahdi and monitored
kernel message. I got following messages before receiving call


DTMF CLIP on 3 68
DTMF CLIP on 3 84
DTMF CLIP on 3 58
DTMF CLIP on 3 78
DTMF CLIP on 3 60
DTMF CLIP on 3 48
DTMF CLIP on 3 60
RING on 1/3!
NO RING on 1/3!
DTMF CLIP on 3 84
DTMF CLIP on 3 78
RING on 1/3!
NO RING on 1/3!
DTMF CLIP on 3 68
DTMF CLIP on 3 68
DTMF CLIP on 3 70
DTMF CLIP on 3 A4
DTMF CLIP on 3 70

But some calls, I am getting long hexadecimall value  as follows,

DTMF CLIP on 3 48
DTMF CLIP on 3 B64
RING on 1/3!
NO RING on 1/3!
DTMF CLIP on 3 84
DTMF CLIP on 3 78
RING on 1/3!
NO RING on 1/3!


Can u guide me on right Mr.Lali and Cohen.. ?

 Hi dears,

 I am from saudi arabia and using asterisk 1.6.2.13,Dahdi-2.3.0 and

 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.

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

[asterisk-users] dtmf Caller-id detection before first ring

2011-05-28 Thread Ashik Ali 
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

Re: [asterisk-users] dtmf Caller-id detection before first ring

2011-05-28 Thread Pezhman Lali 
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
