COMSAT DirectDial℠ Plus

DirectDial℠ Plus allows users to place calls directly to mobile satellite terminals

located anywhere in the world

DirectDial℠ Plus allows users to place calls directly to mobile satellite terminals located anywhere in the world by simply dialing a pre-assigned terrestrial number. DirectDial℠ Plus increases cost efficiencies for calls placed to registered satellite terminals from a fixed or wireless location.


Satellite Calls from Any Fixed or Wireless Line

  • Easy single-stage access dialing using a 10-digit US telephone number
  • Allows calls to a satellite terminal or SIM card from terrestrial and wireless networks world-wide
  • Supports the following call types:
    – High quality and low-speed voice
    – 3.1 kHz Audio used for STU- IIB, fax and low-speed data
    – Unrestricted Digital Interface (UDI) Data used for Mobile ISDN high-speed data or Secure Terminal Equipment (STE)
  • Available for Inmarsat BGAN, Fleet, Swift, FleetBroadband, SwiftBroadband, and other aeronautical services as well as FleetPhone, and IsatPhone Pro. DirectDial℠ Plus is also available for Iridium and Thuraya services
  • Calling Line Identification (CLI)-based access restriction available


Mobility Management

Our global teleport network automatically locates the Inmarsat mobile terminal using Inmarsat’s mobility management system. For services that are not supported by Inmarsat’s mobility management system (i.e., Inmarsat aeronautical services other than Swift and SwiftBroadband), our teleport network employs a proprietary mobility management scheme that can locate a mobile terminal in any ocean region.
