Mid-Call Transfer
This feature allows answered calls to be transferred out to another destination number, regardless of where the call answerer may be, without needing another phone line or having to pay for the cost of making a second call.
This is a network-based feature offering phone system-like functionality over a wide area, so is not restricted to a single location as is a PBX. This feature can be activated on any ICS number in seconds without pre-order.

Hunt Groups
