Conference calling is basically a call that allows voice conversation between three or more individuals. Despite having all the free instant messaging services on the web, conferencing over phone lines is still a very nifty feature. There are several conference call companies that are listed online which offer telephone conferencing – these services are more than the conferencing features that many instant messaging offers.

* FreeConference offers telephone conferencing over telephone lines. Participants can use either web-scheduled conferences for free and the premium toll-free number conferencing that costs only $0.10 per minute. This service is available in the US and Canada.
* Budget Conferencing offers their service at $0.12 per minute. They offer budget conferencing but they assure good service for that value. Their partial list of clients includes McDonalds, Mitsubishi and HP.
* AccuConference has several conferencing call solutions. The can offer audio and video conferencing over the web or telephone lines. Their rates vary depending on the number of people involved, estimated calling minutes and planned number of calls per month. Their services are not cheap though, but their service can be a good option to get more advanced features.

Conference calling companies are becoming cheap with all the great services. One main benefit is that it allows large group conferencing that can involve more of less a hundred participants at a time, longer conference time, telephone recorded conferences, scheduled conferencing and web conferencing as well as software integration with Lotus or Outlook software.
