By the way I am looking for some AT command to include in kannel smsc_at.c as I'm using windows2000 to run kannel, and so I cant' use mgetty. Any idea? Thanks Andrea

Well, as I may send sms by other connections, I just would like to have bearerbox listen to incoming ring, and then habe smsbox call an url passing the caller id, as actually is done when receiving an sms.

GSM 07.07 defines :- "+CLIP: Calling line identification presentation" So, AT+CLIP=1will enable presentation which will be of the format ... +CLIP:, where type is number type from GSM 04.08 10.5.4.7 I've only tried it on a Nokia Card Phone, but it works OK there. best Roy -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Stipe Tolj Sent: 23 August 2001 10:34 Cc: [EMAIL PROTECTED] Subject: Re: Sms answer to a ring call Importance: Low > I am wondering if it possible, > with gsm modem, to listen to phone call, > get the callerid, and replying with an sms to it. > This to save an sms.

>Has someone experience with those stuff?
As Hubert said, I tried with my wavecom,
it's ok.
AT+CLIP=1
OK
RING
+CLIP: "+393479336220",145
RING
+CLIP: "+393479336220",145
So now I'm trying to implerment this in kannel.
Basically I think I have to change (duplicate) pdu_extract,
and give an ATH to close the call after taking the
callerID.
We should also delete from the input buffer all the rings.
It should be something like this:
static int pdu_extract_my(SMSCenter *smsc, Octstr **pdu) {
Octstr *buffer;
long len = 0;
int pos = 0;
int tmp;
buffer = smsc->at_inbuffer;
/* find the beginning of a message from the modem*/
pos = octstr_search(buffer, octstr_imm("+CLIP:"), 0);
if(pos == -1)
goto nomsg;
pos += 2;
/* skip the spaces and line return */
while( isspace(octstr_get_char(buffer, pos)))
pos++;
pos -= 5;
/* check if the buffer is long enough to contain the full message
if( octstr_len(buffer) < len * 2 + pos)
goto nomsg; */
/* copy whatever you want (callerId usually) from the input buffer,
this row has to be changed*/
*pdu = octstr_copy(buffer, 0, pos);
/* delete from the input buffer,
this row has to be changed*/
octstr_delete(buffer, 0, pos);
return 1;
nomsg:
return 0;
}

Forgive me Jorg, I just want to make a try, I really don't want to put it into kannel, at least not in the official release, by the way I'll be really glad if I'll get it :-) Indeed I don't understand why I can accept sms and it's ugly to listen for a ring call.

You should try to compile mgetty, and then how can you run the script? Andrea P.S. please post only to the list, othewise I get them twice.

RE: Sms answer to a ring call
smsc_at does not handle incoming and outgoing traffic at the same time. I think you have no choice but to use 2 ports, or rewrite smsc_at to solve its fundamental problem, and support your own functionality at the same time. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Andrea Viscovich Sent: 24 August 2001 12:07 To: [EMAIL PROTECTED] Subject: Re: Sms answer to a ring call Importance: Low >A simple program (C, Java or whatever) that opens >a serial port, initializes the modem, waits for RINGs and forwards >the caller id through HTTP to Kannel is enough.

Well, maybe in the future I'll have something dedicated only to incoming calls, in the meantime I'll use the same modem to receive sms and calls. Regards Andrea
