If a particular team are tasked with answering calls what happens if they are all occupied? For example, if a sales team are all engaged who deals with call, is that potential sale lost.
With a Hunt Group all calls go to a predefined group in a random order. If the group are all engaged then after a set time another predefined group of people join the Group, to create an expanded Group and all phones in the expanded Group start ringing. The process can be repeated with more individuals joining the Group.
