"The architechture is the best part of the 2600hz stack - it is the only product which can scale into different geographic regions and failover without horrible stretched clusters. The choice of erlang whilst it seems tough at the start is pure genius once you get under the hood.
As a global customer we also engage with their support teams which is also really great."
"2600hz provides very streamlined but also feature-rich VoIP services. Whether you need a simple 1-2 phone office or a sizeable 50-phone company, they have all the features you could ever want."
