Dear Raj,
For test bed we have a single port fxo card which works with Asterisk and costs Rs. 3500/- + 5% Tax
But this card is not recommended in production environments, this is what we stock and suggest for all the new guys who want to have a phone line come into asterisk and do their research projects (several of these cards have been sold in IITs all over india)
Btw writing a voice modem driver would be time consuming n costly affair n still requires a lot of testing, I believe the option I have makes economic sense.
Anyone wants to purchase on can get in touch with me offline.

Infact I found V-Serve Technologies selling some good cards and asterisk IP PBXs as well. I guess they can be reached at vservetech.in, vserve.in
They have a range of 1-8 port IP PBX and IP Phones and Telephony Line Cards that support open-source hardware and software. Typically based on the IP-04 of astfin fame.

Agreed, it would be time-consuming, but it still sounds like a good summer hacking project to me, and if it makes Asterisk more versatile so much the better, no? I mean, how many PBX manufacturers can claim compatibility with the array of devices Asterisk works with, and the more devices it does work with the higher its acceptability.
Not that modems are that much cheaper, but you can still get a decent external voice modem for around Rs 2000, and all it needs is a serial port. Makes sense in a price-sensitive market like India to me.

Offer appreciated. I wish I had the time to work on this, but this is one of the not-so-lean periods for me work-wise, so am not offering anything above the basic idea itself.
Looking at Google, it seems that some (dated) stuff is already available:

Hello,
Quoting "Raj Mathur (??? ?????)" raju@linux-delhi.org:
Sure, I would like to work with local Manufacturers of Voice Modems, since the card that I recommended earlier doesnt get us the callerID from Indian PSTN line.
However, If you are interested I can ship you one of the above card if you got enough time to write the CallerID Patch for Asterisk.
You can get more info from the below URL : https://issues.asterisk.org/view.php?id=6683
Its tentatively fixed for the costlier Digium and Sangoma Full 4 Port n 2 Port Boards, but its not fixed for the Single Port board, which we sell as the Asterisk Starter Kit.
Most Asterisk Enthusiasts have purchased the above card from us without the callerID thing. I still have around 40 of them in our stock.
So considering the Voice Modem, work, the above work (Getting Caller ID on our Single Port FXO Low cost hardware) is fairly more easier.
Due to the above problem, we stopped manufacturing them, but if the same is fixed, I am sure we can beat the Rs. 2000/- mark easily :)
Let me know, Regards, Mitul Limbani, Chief Asterisk Trainer & Founder, Enterux Solutions, www.enterux.com +91-9820332422

I could resurrect my old (1993) Rockwell R9624vDP data voice modems. This one will i/o adpcm encoded data on it's bus and will i/o that on the phone network side. There is a daa circuit too. Which can be replaced with readymade daa.
Any newer modem should be able to do exactly the same. I have used a dlink 56k modem for some such thing in 2002.

With telephone calls getting cheaper every day, does it make a significant difference when using IP telephony? Recently MTNL made calls to the US @ Rs.1 per min. Otherwise, how about those IP phones that directly use LAN ports? I think skype has this phone.
