本文发表在 rolia.net 枫下论坛You Cannot Make Phone Calls or Start Voice or Video Conversations with Windows Messenger
The information in this article applies to:
Microsoft Windows Messenger 4.0
Microsoft Windows Messenger 4.5
Microsoft Windows Messenger 4.6
Microsoft Windows XP Professional
Microsoft Windows XP Home Edition
Symptoms
You may not be able to make phone calls or start voice or video conversations with Windows Messenger. For example, you may receive the following error message when you try to make a phone call:
Your network is configured such that you can not make phone calls.
Cause
This behavior may occur for any of the following reasons:
You are not running the latest version of Windows Messenger or you have not applied Windows XP Real-Time Communication Client Support for Network Address Translation (NAT).
You are running the Zone Labs ZoneAlarm program.
Your home or corporate network or ISP uses a firewall or NAT device that does not support Universal Plug and Play (UPnP).
Resolution
To resolve this issue:
Download and install the most recent version of Windows Messenger. To do this, visit the following Microsoft Web site:
http://messenger.microsoft.com/
The latest release of Windows Messenger includes updates that address several issues that involve voice functionality in Windows Messenger.
NOTE: To have a voice conversation in Windows Messenger version 4.6, both parties must be using Windows Messenger version 4.6. Neither party can be behind a non-compliant firewall or NAT device.
If you are trying to make a phone call from Windows Messenger, download and install Windows XP Real-Time Communication Client Support for NAT. For additional information about this update, click the article number below to view the article in the Microsoft Knowledge Base:

If you are running the Zone Labs ZoneAlarm program and you are trying to make a phone call from Windows Messenger, configure ZoneAlarm to permit outbound traffic to e450.voice.microsoft.com.

Verify with the manufacturer of the firewall or NAT device that is used by your home or corporate network or ISP that the device is UPnP compliant. If not, contact the manufacturer to determine if a UPnP update is available. For example, if your network uses a Linksys EtherFast-series router, contact Linksys to obtain a firmware update that adds UPnP support.

If you can complete your phone call or voice or video conversation successfully with your firewall turned off, it is likely that your firewall is not UPnP compliant. The only way to use voice and video communications with Windows Messenger through a non-UPnP firewall (for example, Microsoft Internet Security and Acceleration Server 2000) is to configure the firewall to allow incoming traffic on UDP ports 5004 through 65535.
More Information
For increased security, Microsoft has upgraded the voice technology for Windows Messenger version 4.6. Microsoft recommends that you use the phone, voice, and video features of Windows Messenger only with a firewall or NAT device that is UPnP compliant. Internet Connection Sharing (ICS) and the Internet Connection Firewall (ICF) in Microsoft Windows XP are UPnP compliant.
If you have any questions about whether you are behind a firewall or what type of firewall you are using, contact your ISP or your corporate helpdesk, or use the Microsoft Windows XP Help and Support Center (see the "Internet Connection Firewall Overview" topic).
To obtain the best results when you are using a NAT device, make sure that you have the latest version of both the firmware and software for the device. These may be available from the manufacturer's Web site. For more information about updating your device or software, see the NAT device's documentation.
