Esiste un software tipo NetMeeting che permetta di chiamare direttamente via
modem/telefono senza utilizzare Internet ed i servers ILS?

modem/telefono senza utilizzare Internet ed i servers ILS?
Dovrebbe bastare installare Server di accesso remoto sul pc che riceve
la telefonata e poi connettersi con Netmeeting a quell'IP. Ma non so
quale sara' la qualita' video visto che la connessione sara' a 33600
bps.

 The videoconferencing application (NetMeeting, CU-SeeMe, …) itself
Installation
Preliminary note: as stated above, I highly recommend using the version 1.3
of the Dial-Up Networking (DUN) because this version, as opposed to previous
ones, does not require any configuration of IP address and this avoids the
related issues (especially the required reboot after the configuration of
the IP address.) DUN 1.3 is pre-configured with its own IP addresses:
192.168.55.1 for the server and 192.168.55.2 for the client (or connectoid.)
DUN 1.3 comes with Windows 98 and later, but if you still use Windows 95,
you can download it from Microsoft’s web site (see Additional Resources
below) or if you install Internet Explorer 4.0 or later.
If you don't have an Internet access yet you need to make the 2 or 3
following steps:
* Install the Dial-Up Networking:
In Control Panel double-click on Add/Remove Programs. Select the Windows
Setup tab. Highlight Communications in the list and click Details... In the
dialog box that shows up, check the box in front of the Dial-Up Networking
option and click OK.
* Install a Dial-Up Adapter and the TCP/IP protocol:
In Control Panel, click on the Network icon. In the Configuration tab, push
Add and choose Adapter then Add, select Microsoft/Dial-Up Adapter then OK.
Next install the TCP/IP protocol (if it is not already) this way: Add,
Protocol, Add then choose Microsoft - TCP/IP and OK.
Note: if TCP/IP is installed for your network board (NIC) and it is not
useful for this purpose you can safely remove it.
* Setup TCP/IP:
If TCP/IP is already installed and configured on your computer so leave the
settings as they are, only modify the IP Address. In general default values
will suit your needs.
Bindings: nothing to do
Advanced: nothing to do
DNS Configuration:
        Disable DNS
IP Address
       If you use DUN 1.3, select Obtain an IP address automatically and
skip to next tab (WINS Configuration), otherwise:
       select Specify an IP address
       enter the IP address2 you want for your computer in the IP Address
field (e.g.: 192.168.0.1)
  enter the subnet mask. This will be 255.255.255.0 since only class-C IP
should work.
WINS Configuration:
        select Disable WINS Resolution
Gateway: nothing to do
Press OK. Windows will surely ask you to restart your computer to take the
changes in account.
* Install the Dial-Up Server1:
If you still use Windows 95, you will need the Plus! pack for Windows 95. If
you already installed the Plus! pack in its entirety so the Dial-Up Server
is installed on your computer. If not already installed, the only thing
required from Plus! for the link is the Dial-Up Server, no need to install
other optional things.
If you use Windows 98 and later, the Dial-Up Server is part of the system.
If it is not installed yet (i.e. it does not show in the Connection menu of
the Dial-Up Networking), open the Control Panel, double-click Add/Remove
Programs, select the Windows Setup tab, double-click Communications. In the
Communications dialog box, check Dial-Up Server. Click OK to close this box
and click OK again.
* Install the driver (Video for Windows compatible) for your camera:
If you have a Windows 95 compatible product you can let Windows 95
auto-detect it: in Control Panel run the Add New Hardware applet, click
Next. When the wizard says Do you want Windows to search for your new
hardware ? you can select yes (recommended), click Next twice and let it
go...
If you don't want to wait all that time, you can manually add it by
selecting no to the question above and click Next. Then select the Sound,
video and game controllers option in hardware type and click Next. Select
the appropriate manufacturer and board model if you find them in the list or
click Have Disk (you'll have to provide the diskette provided to you with
the product.) Press Next again and Windows shows you the resources3 used by
your hardware click Next and then it tries to install the drivers. If you
want to modify the default settings of your frame grabber you'll have to do
that later4. When it's done click Finish.
Windows will surely ask you to restart your computer to take the changes in
account.
Note: this is a very generic installation procedure, I highly recommend
following the instructions that you got with your camera to install it.
* Create a connectoid (a connection icon):
On the client side, create a new connection. Select
Start/Programs/Accessories/Dial-Up Networking. Double-click Make New
Connection. Enter the name of the person you want to connect to (or whatever
you like) then click Next. Enter the Area Code (optional), the Telephone
number and the Country Code, click Next and if everything is OK click
Finish. Now you have a new icon in the Dial-Up Networking folder.
Right-click on this icon, select Properties in the dialog box click/select
the Server Type... button/tab. You can uncheck the Connect to a network,
NetBEUI and IPX/SPX compatible options. Click TCP/IP Settings... In this new
dialog box, just select IP address assigned by server if you use DUN 1.3 and
click OK. Otherwise select Specify an IP Address and enter the IP address
you want to use for the client computer5 (e.g.: 192.168.0.2). Keep other
options to default and click OK. You can close all the opened dialog boxes.
* Now you can install your videoconferencing application.
You are now ready to start a link.
How to establish the link
* On the server side:
open the Dial-Up Networking folder with Start\Programs\Accessories\Dial-Up
Networking. Select the Connections/Dial-Up Server menu. In the dialog box
that shows up select Allow caller access6 and click OK. Launch the
videoconferencing application. You are ready just wait for the client to
call.
* On the client side:
Double-click the icon of the connection you created in Dial-Up Networking
and click Connect. When the connection is established a little box with a
Disconnect button will show up. You'll just have to press this button to
break the link.
You can now run the application. If you use NetMeeting, select the Call /
New Call menu and enter the IP of the remote computer in the To field of the
Place A Call dialog box:
- if you don't use DUN 1.3, enter 192.168.0.1 (if you followed the examples
above) or
- if you do use DUN 1.3, then enter the predefined server address, i.e.
192.168.55.1.
Leave Automatic in the Using field.
Press the Call button.
That's it. Enjoy !

FAQ: 
http://noeld.com/genfaq.htm#M1
1 You need to install the Dial-Up Server only on one of the two computers
(the one you choose to be the server) but if you want to be the server and
the other one the client and conversely so you need to install Dial-Up
Server on both sides.
2 You can use any IP address you want but 0.0.0.0, 255.255.255.255 and
127.0.0.1 and of course a different one than the one used on the machine on
the other end of the link. To be honest the range of IP you can use is
smaller because some IP are reserved for broadcast and multicast features.
It is recommended to use the IP address in the reserved range: 192.168.0.1
to 192.168.255.255. You will have to switch back the Obtain an IP address
automatically option the next time you want to access the Internet. This
will requires to reboot.
3 If you want to change the resources allocated for your camera or video
capture card, right-click on the My Computer icon on your desktop and select
Properties. In the System properties dialog box, select the Device Manager
tab. Expand the Sound, video and game controllers branch, select your
hardware and click Properties.
In the Video Capture Properties dialog box select the Resources tab. In the
Resource settings list, choose the resource you want to change and click
Change setting... Click OK to finish.
4 In Control Panel double-click on Multimedia and select the Advanced tab.
In the Multimedia devices list, expand the Video Capture Devices branch.
Select your hardware and click Properties. In the dialog box that shows up
click Settings and modify the settings to suit your needs.
5 If you have a Network Interface Card (NIC) in your computer using TCP/IP
the address you choose here must be different of the one(s) used by your
NIC. This address must be different from the one of the server that you will
call.
6 When the link is over do not forget to reset the No caller access option
in the Dial-Up Server. If you forget and share the line with your phone the
server will answer each time a call is detected and that can be boring.
Alternatively you can choose to turn off your external modem when the link
is over so that you won't have to worry about this option.
