At Gram Vaani, we are building telephony support through FXO and E1 
cards. These are PCI cards that go into a computer, and so calls can be 
received/made through software itself. Therefore stations just need to 
get a phone line and then plug the line into the card instead of into a 
telephone or hybrid.

This setup gives us the advantage of being able to control the telephony 
channels to interpret DTMF signals. So we can actually make telephony 
applications such as press (1) to record an ad, or press (2) to leave an 
farming related question, or press (3) to request for a song, etc. 
Recordings for advertisements or questions and answers can later be 
broadcast through radio. A hybrid on the other hand will only give 
access to the input and output analog audio.

The second advantage is that we are integrating all of this with the 
GRINS interface. So now the RJ can receive calls through the GRINS 
interface, and doesn't have to tinker with hybrid volumes and picking up 
the phone, etc. GRINS will also keep track of all recordings for 
advertisements, questions, comments, etc, so all the content can be 
managed centrally.

The telephony service will be out in another month or so. Then stations 
just have to download GRINS and buy an FXO card. Single channel FXO 
cards are available for hardly Rs. 2000, and higher end cards can also 
be purchased if a larger number of simultaneous calls are to be handled. 
We will publish all these details very soon.
