Digital Voice Services

This is a IP phone provider based on Great Vancouver, BC Canada.
Let’s see how it works.

For my parents in Shanghai, I think it is better to buy it and send the adapter to them. Connect it to the high speed internet and plug the regualar phone set.
I can call them with (604) area code to them as a local phone call.
This is a way I will use it. Another one is I use it instead of my currently Telus phone service.
Their rate is cheaper than that of Telus.

VoIP Technology

This is from Fierce VOIP
The foundation of VoIP networks and VoIP technology is a set of protocols called H.323. These protocols were established by the Telecommunications Sector of the International Telecommunication Union (ITU-T). H.323 specifies components, protocols, and procedures for real-time point-to-point and multipoint multimedia communication over packet-based networks. It also sets interoperability guidelines for communication between H.323-enabled networks and other conferencing standards.

Defination of VOIP

From Vonage

Voice over Internet Protocol (VoIP) is a reliable technology for transmitting ordinary telephone calls over your internet connection using packet linked routes, also called IP Telephony . Internet Protocol involves the transmission of telephone calls over a data network like the Internet that can reach any telephone on the public-switched telephone network (PSTN).


Voice over IP (also called VoIP, IP Telephony, and Internet telephony) is the routing of voice conversations over the Internet or any other IP network. The voice data flows over a general-purpose packet-switched network, instead of the traditional dedicated, circuit-switched voice transmission lines.

From Encarta Reference

Voice Over Internet Protocol (VOIP) is a method for making telephone calls over the Internet by sending voice data in separate packets, just as e-mail is sent. Each packet is assigned a code for its destination, and the packets are then reassembled in the correct order at the receiving end. Recent technological improvements have made VOIP almost as seamless and smooth as a regular telephone call.

Session variables problem

I met the session variables problem in IIS6.
I use global.asa as web application.
Same coding, it works under IIS5 of windows 2000 and IIS5.1 of windows xp, but it lost session variables under IIS6 of windows2003.
Sometimes I need to log in more than one time to get in the required page.
Tonight, I solve the problem.

Microsoft introduced several new features into Windows 2003/IIS6
webserver that affect how sessions and application pools are handled.
*Application Pools*
Most webhosting companies host multiple websites in the same application pool. When resources are maxed out for a application pool IIS 6 starts to recycle these sites causing application variables to be lost for those recycled sites.
If you are experiencing application/session loss symptoms then we would recommend asking your webhosting company to place you in your own application pool with all recycling options disabled and the recycle worker process set to recycle only once during the day at a set time.

I made a new applicaiton pool which is used by my application only.
So the problem disappeared.
Steps as below:
Step 1:
Add new application pool.
