 |
|
Hi,
I am working on building a basic payphone application on Windows that
connects to a standard fixed wireless CDMA phone on a serial
interface. While I've worked on Windows desktop apps that use CDMA
data connectivity (using RAS API), I don't have much knowledge on
voice telephony integration and specifically, on interfacing required
for building a payphone application. For this, will be great if I
could get some pointers on:
* Do all CDMA phones use a standard AT command set which throws events
such call-connected, call-ended which I can capture on my PC-side
serial listener for call metering?
* Where can I find details on the command sets used in CDMA phones -
for voice telephony integration?
* Typically, what are the features a basic payphone application needs
to support? Is there info / documentation / guides / open-source
software available on this on the web? I tried googling around but
maybe I'm not searching for the right things.
At this stage of initial cluelessness, any help would be hugely
appreciated.
Thanks,
Moa |

There are many CDMA/WCDMA technical books that have been posted over in
newsgroup alt.binaries.e-book.technical in the past few weeks, such as:
CDMA Systems Engineering Handbook - J. Lee, L. Miller (Artech House, 1998)
WW.pdf
A huge series of Electronics books was posted over the last few months in
that newsgroup with lots of cellular engineering books you may find of
value. This series of books can be easily identified in the Subject list
because the list is broken up into numbered sections, each of which has its
own set of PAR files to correct errors. It's an amazing library.
