Conference Call Providers

I’ve tried several. The best one seems to be Rondee’s https://www.rondee.com free conference calling service. But, I’m wondering if people have experiences with other providers. I’d like to get data without having to try each one.

I am a member of a non-profit service group. Because we are scattered across the DC area, we use conference calls often. We are currently using our office conference number, but I don’t think we can continue. Given our limited budget, does anyone know of a free or at least very cheap conference call service that we can use? Thanks!

I am looking for a conference call service in India that is pay per use. I should be able to set up a conference call, invite a number of people ( say 10) and they will call in to the number and enter a pin code and be allowed to participate.

Please note that Skype or similar PC based solutions have nt worked for us very well as I find the quality of those services is variable. I am looking for the clarity and predictability of the land line service, and willing to pay per minute charges for certain important business meetings.

Thank you for the any pointers.
