Free conference call service InstantConference.com has been around for more than 10 years. I remember using it back in 2008.
And actually, InstantConference.com has other paid conferencing plans for more users and more minutes and more features.
How to Cancel Account
To close your InstantConference account, there is not an easy one-click way to do that. You’ll have to contact Support at instantconference.com/contact-conferencing-support.aspx – the contact form requires conference dial-in number, access code, contact phone number, email, name, and put “close account” in the subject and description.
