Network & Operations
Problem
Is it possible to use an analog
dial-up connection?
I have broadband but is it
compatible?
Can I use my router with
KNS?
With a high-speed modem
connected directly to my PC
running Windows® XP, KNS
does not work.
I am using a high-speed
modem connected directly to
my PC, but the modem is
inside the router.
We recommend a broadband connection. Otherwise, if
you have a narrowband connection of about 50kbps, it
might work, though this will depend on network traffic
conditions. You must also expect to encounter some noise
and to lose audio contact intermittently.
Yes, it is compatible provided that your ISP provides a
global IP address, VoIP ports, and a command port.
We do not guarantee that KNS will work through a router.
Nevertheless, if your router offers DMZ or "virtual
computer" features, you may be able to set it up by
yourself to enable KNS to work properly.
You will have to make the required adjustments, referring
to the instruction manuals for the devices you are currently
using, at your own risk. Generally speaking, you can use
any modem that is compatible with Microsoft®
NetMeeting®. If your operating system is XP, switch off the
ICF (personal firewall) provided by Windows®.
If the ICF (personal firewall) of Windows® XP is switched
on, you should switch it off; however, be aware that this
can represent a security risk.
Switch to a modem that is not inside a router.
Open the ports required for KNS: a command port and
H.323 control ports (if the router is compatible with
Microsoft® NetMeeting®).
If you must use a router with built-in modem, try setting
up a bridge. In this case, however, some ISPs will not
issue an IP address. To solve this, you can either set up
another router (compatible with Microsoft®
NetMeeting®) externally, or have an IP address issued
using a PPPoE* client.
(A PPPoE* client is available as a standard feature of
Windows® XP.)
Be aware that you do all of this at your own risk.
