Sabeer Bhatia's Sabsebolo (audio conferencing service) has shutdown citing regulatory issues.
"With deep regret, we have to inform you about the suspension of our services due to a regulatory issue. Rest assured we are working on getting it resolved. We realise how much our customers have been used to the services and we are deeply indebted to each one of you for your reposing your faith in us."
What alternatives to Sabsebolo do you recommend?
