The ICG Sigma-7 retractor reel handset is similar to current aeronautical handsets in appearance and form factor but is much simpler and more conventional in its use. No external power is required other than a telephone circuit connection. This telephone, with the option of 2-Wire or 4-Wire, provides the familiarities and conveniences users are accustomed to when using a telephone. Without complex menus or functions to learn or understand, it is the preferred solution when a customer requirement is for simple and conventional calling procedures.

The ICG Sigma-7 can be recessed into a drink rail or bulkhead mounted with a coiled version available. ICG offers an optional data jack (RJ-11) located in the cradle. This averts the requirement for the completion center to provide a separate jack. The data jack can be either paralleled with the telephone circuit or can be connected to a separate circuit so that both telephone and data calls can be active at any time. The ICG Sigma-7 has an internal magnetic stripe reader to support credit card calling and a special function key to provide enhanced features such as flash transfer and access to programming menus, permitting audio level adjustments, LCD brightness, etc.
