I compiled the following instructions for my family and
friends, so we can enjoy messenger, maybe it can help you.
MSN Messenger 6.2 or 7.0 audio/video enable:
1. When using a high speed Internet connection, the
modem/router MUST be UPnP compatible and have this option
active. For MSN Messenger, both sides MUST have Windows
XP, not so for Windows Messenger. Zone Alarm can be
either on medium or high, but MUST be set it to ALLOW the
MSN Messenger all access to the Internet, this because of
the dynamic ports use for Audio and Video by Messenger.
2. On the Network Connections, right click Local Area
Connection, go to Properties, and the General tab should
show a check mark only on Client for Microsoft Network,
and Internet Protocol (TCP/IP). No check on File and
Printer Sharing for Microsoft Networks, nor on QoS Packet
Scheduler.
3. The Windows Firewall should be ON (recommended) and no
check in Don't allow exceptions, the Exceptions tab will
later show the MSN Messenger and UPnP Framework as being
active ( this is because MSN Messenger detects the UPnP-
enabled Windows Firewall and configures it
automatically, not so with the non UPnP-enabled
ZoneAlarm ). More on firewall and port opening can be
read in the link below:

oy/worki01.mspx#EGAA
4. In the Control Panel > Add Remove Programs > Add
Remove Windows Components, scroll to Networking Services
and remove all checks, except for Internet Gateway Device
Discovery (see A below), and for UPnP User Interface (see
B below). Click Ok, Next, and after clicking Next
(critical step) the Windows Components Wizard will only
then run. Click Finish; now the UPnP will automatically
open all required ports. Each time you run this Wizard,
with the MSN Messenger turned off, the UDP and TCP ports
change numbers automatically. With Messenger off, you can
see how dynamic the port numbers for Audio and Video are
each time you do the Wizard, by accessing Control Panel >
Internet Gateway > right click and select Properties >
under General tab clicking Settings.
5. Sign in on Messenger and run Audio/Video Tuning
Wizard. In the Tools > Options > Connection tab, you
should read You are connected to the Internet through a
UPnP symmetric NAT (Administrator), if on a ADSL line in
my case in PR; if you are using a dial-up line it will
read You are connected to the Internet using a direct
connection. Now check the Windows Firewall Exceptions
list, the MSN Messenger 6.2.0205 and UPnP Framework will
now have a check marks and the required ports
automatically opened.
6. Both Windows XP users sides should have similar
setups, with working webcams and microphones. Remember
that one side can have dial-up and the other a UPnP
compatible modem/router.
(A) Allow you to find and control internet connection
sharing hardware and software that uses UPnP.
(B) Display icons in My Network Places for the UPnP
devices detected on the network; also opens the required
Windows Firewall port.
