We picked an odd time to implement new technology—as the entire country was locking down. But it was fortunate that we rolled out Stelarium when we did, because it’s helping us continue doing important work and was a vital tool for staff working from home during the lockdown.

Dennise Reynolds

It is always a pleasure to work with folks at Stelarium over the chat. It is a differentiating factor from other voip vendors I have experienced in last 4 years. It makes choosing voip vendors easier. Great job guys/girls !!
