Collaboration is no longer limited to just voice of telephony. Modern collaboration involves an omni-channel approach, which includes the follow modalities: persistant chat, text, voice, video, and voicemail. Many Collaboration platforms combine the modalities and feature hybrid architecture. No more are solutions local or in the cloud, but rather are all of the above. Contact center is considered part of Collaboration as well.
