TeleConference Call Service in India?

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.
