An inbound call center is a more advanced business phone system that normally include IVR (interactive voice response) application, advanced call routing, agent management, workflow automation, CRM integration, and agent productivity tools.
Voicent's PBX features already cover most of the inbound call center features. With Agent Dashboard, Manager Dashboard, built-in CRM, and integrated workflow engine, you can setup your inbound call center with little effort. The following video is an example for setting up a quick inbound survey.
A simple workflow is a task that carries out automatically based on some event in the system. Bacause Voicent is an integrated platform, you can design and implement your process automation easily.
