Hi Guys,

I am in Delhi and have MTNL service. Recently I started looking into Modem Caller ID feature and thus came to this forum.

I just wanted to let you guys know that I have tested my modem for caller id and its working well. Initially I wasnt able to retrieve any information out of it except in the Terminal Window.

I tried many professional Caller ID softwares but none of them retr. this info.

Ultimately as a last resort I wrote a VB code to retrieve this info and was able to successfully get caller number into my program.

I noticed 2 things that in Delhi, MTNL( as I am mtnl subscriber ) they transmit only the number of the caller. So thats the only information which you can get. But in other countries( I know of Canada as I was there for 3 yrs ) they send Number, Name, Date/time too. This is why some commercial softwares, which are configured to retrieve information only in a set pattern(eg: DATE xxxxxx,TIME xxxxxx,NMBR xxxxxxxxxx ,NAME xxxx), are not able to retrieve caller number(MTNL send only xxxxxxxx) which is recieved by your modem, which you can see in terminal window but not anywhere else.

Secondly this information is sent between the first and the second ring. So you can not utilize the bann caller feature of many commercial softwares efficiently. It WILL bann the call, but only after the first and second ring. So a little inconvenience.

But apart from that every things working cool.

For your information I bought a really cheap(Rs.200) iNTEX Smart Link SL2800 chipset modem, updated the drivers from www.driverguide.com and enabled the AT#CID=1(my modem's caller ID command, your's can be different) command in the advance tab of modem properties.

And if you are ready to spend some money, one of the commercial software(only one for me), which after a couple of hit and trial, settings etc was able to retrieve the number is Ascendis Caller ID available at http://www.ascendis.com/ . Their software can detect your modems caller id feature, if available or not, CID commands of modem and possible repair/fix of modem so that it sends info correctly to software( only if CID feature is present in your modem ). So I guess its a pretty cool sw for a low price of 35$.


Thats all. If you want to know about my VB code, mail me or check my site in a months time as I will be posting the complete procedure there(www.keysnclicks.com).


I hope this was of some help to some one.

Have fun..

Actually whether u get CID or not depends on the chip on the modem. Brands like US robotics, GVC multitech etc are geared for the FSK interface and will not detect CID on BSNL or MTNL lines coz they use DTMF format. Only way to use these brands is to use FSK to DTMF convertor.

Fact that u are able to receive callerID is not only due to the software but also coz ur modem hardware is supporting Indian CID signals

Thanks for the Info though, we were looking for a cheap brand which would work on our telephone lines.

Hi there,I never said that its just because of my software or vb code. Actually it is because of the chipset on my modem. BUT the thing is many of us are able to see the number being recieved in the hyper terminal but then this number doesnt shows up in any other software. And this is becausethe waythese s/w's are configured.. they only detect this information if they see the following string in the modem output : "NMBR", "NAME", "TIME, "DATE" i dont know if anything else is relayed by the telephone companies... In India specifically in MTNL no such strings are released only the number is sent..that all.. so these software's display messages like"No Number Available" or "UNKNOWN".There is one thing that iam still interested to know if any one knows about it... the NUMBER information comes between the first and the second ring only.. Is there a way or harware to alternate this behaviour... May be the first ring just doesnt ring on my phones and thus i get the Number before anything else..If any one knows anything regarding this, let me know by mail or here in the board.Thanks and Cheers,Amit

I dont think there is any way to do that at the consumer level. The info is coming in a particular way coz the exchange is sending it that way, i cant think of any way to alter this behaviour other than a change of equipment at the exchange.and yes indian telco's only give the telephone no..no date/time/name etc

i got a dtmf to fsk converter for 300rs, (seller calls it caller id converter) and my modem now shows the calling numbers. most products look like a splitter but it is the converter and its working fine.
