Planning to buy a new web conferencing software? Do keep in mind some points before you make that purchase.

Price:
The price may range from free to several thousand dollars. Don't assume that a higher priced product is better. To a certain extent, you get what you pay for, but a few of the freeware products are actually stronger than some commercial products. So, find the best software that would meet all your requirements.

Operating System Support:
It is a key determining factor, especially if circumstances require you to run conferencing from an existing web server.
Compatibility with Other Environments:
If all access to your conferencing system will be made via the web, then compatibility with other environments is not an issue. But in some cases, there is a requirement that discussions be accessible by some other means. This limits your choice.
Administrative Capabilities:
If you have limited access to your web server, you'll want to choose a product that can be installed and administered easily with whatever level of access you have been granted.
Browser Support:
Some web conferencing systems rely on advanced HTML extensions such as frames or Javascript. So, before purchasing the software, be sure the software chosen is compatible with your system.
Just keep these key considerations in mind and you are sure to buy the best!
