Now more than ever, organisations across the public and private sectors depend on seamless, secure, and high-quality communications. Even with an increasing range of channels having established themselves in recent years - including voice, email, video, and SMS - voice services remain a key part of how we communicate and collaborate.

In our offices, businesses, colleges and homes, barriers exist between people that hinder free and easy communication. Physics undergraduates rarely mix with the Philosophy students, our accounts teams tend not to lunch with our account managers, and I almost never speak to the lady who lives in the flat below mine. It's a natural result of living, working and studying in cities with millions of strangers.
