Dear All,
I have asked this question before, but because of my problems with
subscription to this list, I was not able to read any of your
responses. And since there are no official archives I am asking it
again. Kindly bear with me; and if necessary use the delete key
judiciously.
I have an Intex external modem (http://www.intextechnologies.com). To
go online, I dial my ISP using the phone line.
What I want to do is to be able to make a phone call (and talk to the
person at the other end) from my linux box, through the modem. Kindly
let me know if this is possible.
Also pointers to other relevant information would be very useful.
Thank you for your time.
Cheers,
anna

This version of the question is a bit more vague than the one you posed
before. Then, I believe you said you had a headset plugged directly into the
modem (not, for example, into your sound-card ports), and that you could
hear the party on the other end of a phone call but not be heard when you spoke.
It's likely that the modem uses some non-standard AT command to turn the
mike on and off (in contrast to the speaker, which turns on and off with a
long-established, standard AT command). If that's so, and you can find the
command in the docs, then it should be possible to control the mike from
minocom (or whatever Linux terminal software you use), or even to write a
small, custom app. Regrettably, the manufacturer's site isn't well orgainzed
for serious research, offering more glib marketing info about the modem than
substantive information about its operation (at least that I could find), so
you'll have to consult the docs that came with the modem to try to track
down the needed command.
The other option is to do the whole thing through Linux. The standard app
for this is vgetty (which also does answering-machine-type functions), but I
haven't used it, so beyond giving you this starting pointer, I fear I won't
be of much help with this approach.

Wow. You are absolutely right. Not only did you read my previous
mail, but you remember it for a couple of days! (Or did you refer
back?) I would have probably typed in the rest of the information in
my next query. ;-)

I will do this. Once I know that its possible and can be done, then
I'll be more enthusiastic to struggle for setting it up. First step
is to find the docs for my modem!

I have just now downloaded its documentation. I'll go through it and
see how I can make the best use of it. Thanks for this
just-what-is-needed pointer.
Cheers,
anna

I have got hold of the manual provided with my modem. I am perusing
the manual for the past half an hour or so, but am not very sure about
what to look for. There is no mention of mike anywhere in the manual.
(But there are a handful of commands for the speaker.)
I am quoting here two appendices from the manual, which I think might
contain the relevant information. Could you please help me to figure
out, which of these AT commands are for the mike? Or is the relevant
information not available in the quoted text?
If any of you think that you can help me with this, kindly let me
know. I'll send you the entire manual in PDF off-list (260384 bytes).

Appendix 2 AT command set
Executing commands
Your modem is in Command Mode upon power-on and is ready to re-
ceive and execute AT commands. The modem remains in Command
Mode until it makes a connection with a remote modem. Commands
may be sent to the modem from an attached terminal or a PC running a
communication program. This modem is designed to operate at com-
mon DTE speeds ranging from 115.2 Kbps to 300 bps. All commands
and data must be issued to the modem using one of the valid DTE speeds.
AT commands and format
All commands must begin with the AT prefix, followed by the command
letter and ended with the ENTER key. All default settings are printed in
bold text. Spaces are allowed in the command string to increase com-
mand line readability but are ignored by the modem during command
execution. All commands may be typed in either upper or lower case,
but not mixed. A command issued without any parameters is considered
as specifying the same command with a parameter of "0".
Example: ATL [ENTER]
This command causes your modem to lower its speaker volume.
AT Command Summary
All default settings are printed in bold and italic text.

isn't it too much data on a maximum of 33.6kbit/s for h.323 data transfer?

Tom -- I think you missed earlier emssages in this thread. The original
poster is trying to use a modem equipped with *built-in* voice to make a
phone call. The mike connects directly to the modem, and all that's needed
(I think) is a command to turn it on. Nothing is being digitized, as I
understand it; the modem is simply acting as a normal (analog) telephone.
