3 1 Overview Vobal Technologies has developed the Vobal S2 System: a prepaid Voice over IP (VoIP) telephony service that utilizes a unique, propriety, and patented protocol designed specifically for use on Inmarsat FleetBroadband and BGAN Standard IP Data circuits. Vobal VoIP has been independently certified1 to provide high quality voice service with Standard IP bandwidth consumption being less than 0.05MB, per minute. This low bandwidth usage by an established product means that Vobal s systems are the first commercial solutions to meet the data usage requirements of Very Large Allowance (VLA) pricing plans. Vobal Technologies also provides the only VoIP technology that provides multi-satellite telephony service in hybrid environments which use failover routers. This unique capability includes automatic adjustment and notification of end user VoIP termination rates based on cost of bandwidth considerations related to the actual satellite backhaul used to terminate VoIP traffic. One advantage of this system is that it is, in theory, poised to handle future Global Xpress routed traffic as well as today s standard FBB, though, of course, robust testing will be performed once Global Xpress becomes available. 2 Hardware 2.1 Vobal VoIP System (S2) The basic VoIP configuration consists of a VoIP server (small microcomputer), Cisco Voice Gateway and analog telephone. 1 Bandwidth and Quality Analysis Illinois Institute of Technology Vobal Technologies VoIP for FleetBroadband and BGAN Page 1

5 3 VoIP Technology 3.1 Proprietary VoIP Protocol Vobal Technologies utilizes a unique, patented protocol which provides high quality voice, optimized for transmission via satellite connections with low-bandwidth, high delay, and high jitter. Highlights: One Vobal VoIP telephone call uses ~6 kbps (total) of bandwidth per call, on average. Vobal significantly compresses media and provides voice quality which is comparable to telephone services which utilize considerably more bandwidth. Lab measurements of the Mean Opinion Score of Vobal VoIP voice quality is 3.34 versus 3.4 for a typical satellite telephone call and 3.7 for a typical VoIP call over an ideal land network. Vobal VoIP overhead is greatly reduced compared to standard VoIP Vobal VoIP Idle bandwidth is less than 5 MB per month for an entire system, including multiple phones Vobal VoIP telephone traffic on FleetBroadband Standard IP consumes less than 0.05MB, per minute 3.2 Independent Validation of Vobal s VoIP Protocol VoIP Lab at Illinois Institute of Technology Packet Headers*: Ethernet and IP Packet Headers*: IP Only Simultaneous Calls Kilobits per second (kbps) MB as 1,048,576 bytes Megabytes per minute (MB/min) MB as 1,000,000 bytes Kilobits per second (kbps) MB as 1,048,576 bytes Megabytes per minute (MB/min) MB as 1,000,000 bytes One Three (for each call) Note: Satellite system data transfer protocols do not include Ethernet headers, only IP headers.

6 4 Making VoIP calls using Vobal Vobal VoIP is a prepaid service. VoIP telephone service can be funded in several ways - depending on specific customer requirements. 4.1 Shared line Typically, in situations where multiple Crewmembers or Passengers will be accessing the Vobal VoIP telephone service, prepaid airtime is sold in the form of pre-paid PIN Codes. The value and denomination of these pre-paid PINs are established during the sales order process. Initiating a ship-to-shore telephone call Prior to initiating a telephone call, have your PIN code available. 1. Pick up the telephone and listen for a dial tone. A dial tone indicates the VoIP telephone system is operational and ready to provide service. 2. Input your destination telephone number using the following convention <country code><area code><telephone number> Example of call to New York City, NY, USA The Vobal VoIP auto attendant will ask for your PIN code Carefully input your 12 digit PIN 4. The auto attendant will inform you of the remaining balance (in minutes and seconds) of your pre-paid PIN. 5. The telephone call will be processed 4.2 Dedicated line Sometimes a ship will choose to have a dedicated line set up (for ship s business, for instance). These lines do not require entering a PIN code prior to each call, but are funded through a number of other ways that may be established during the sales process. Initiating a ship-to-shore telephone call 1. Pick up the telephone and listen for a dial tone. A dial tone indicates the VoIP telephone system is operational and ready to provide service. 2. Input your destination telephone number using the following convention <country code><area code><telephone number> Vobal Technologies VoIP for FleetBroadband and BGAN Page 4
7 Example of call to New York City, NY, USA The auto attendant will inform you of the remaining balance (in minutes and seconds) of your dedicated line. 3. The telephone call will be processed 4.3 Receiving incoming (shore-to-ship) telephone calls The only requirement for receiving telephone calls is to insure that the VoIP telephone system is online and connected to the internet. The internet is available when the FBB or BGAN unit s Standard IP Data circuit is active and connected. Please note that shoreside correspondents calling your telephone number will also be informed of your prepaid balance (in minutes and seconds remaining for the call, not in dollar value) prior to the call being connected. 5 Installation Instructions 5.1 Equipment Contents S2 Server + power adapter cabling (small black computer) Two (2) Ethernet cables one blue, one yellow Analog Telephone + cable (RJ11 connectors) Analog Telephone Adapter (ATA) + power cabling Unit that connects the S2 to the Internet and to the analog telephone or PBX 5.2 Equipment Setup 1.

Connect one end of the blue Ethernet cable into the blue port of the ATA (Internet) and the other end into the Internet source. 6. Connect the ATA power cord to both the ATA unit and the power source. After several seconds you should see 2 green lights on the ATA indicating power and Internet. If you do not, check that the Internet connection is live and that power is applied to the ATA. Example: Note: The ATA provided may have 2 Phone lines rather than a Phone and Data line as shown in this photo. 7. Connect the S2 Server s power cord into the power source. 8. If less than 30 seconds have passed since powering on the ATA, wait. Otherwise power on the S2 Server by pressing the power button on S2 front panel. 9. After about 2 minutes, a third green light on the ATA lights up indicating that telephone service is available. 10.
