Optistreams Voice over VSAT  

Optistreams carrier-class VO-VSAT Phone service enables customers to make clear digital telephone calls, in addition to receiving business class Internet access, and real-time video over the same high-performance satellite link. Unlike traditional VoIP based services that leverage the open public Internet to provide inexpensive long distance calls, Optistreams VO-VSAT IP Phone, is a carrier class service that is directly connected to the public switched telephone network (PSTN) and provides toll quality calls and satellite phone lines that are FCC 911 compliant. Voice and data channels are completely separated, actually operating on different frequency channels, to ensure a high Quality of Service for mission critical applications like emergency response, oilfield operations, or business continuity. In addition, VO-VSAT Phone supports analog plain paper fax services as well as a variety of IP-based devices.

The service is available as an option with Optistreams  Aetheron/IDirect Series  VoIP solutions provide:
  • Affordable solutions that combine both voice and data on one system
  • High quality voice service
  • 4-digit dialing around the world
  • Voice enhanced websites
  • Multiple plans and configurations
  • Flexible, combined billing services
  • Configurations for any number of employees
  • Personal phone numbers and phone settings, including voicemail and conference calling
  • Reduced cost for reconfiguring systems in the event of moves or relocation
  • Mobile/Transportable packages with satellite Internet
General Information About VoIP Voice over Internet Protocol (VoIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular (or analog) phone line. Sometimes referred to as IP Telephony, Internet Telephony, Broadband Telephony, Broadband Phone or Voice Over Broadband, VOIP can be deployed on any IP network. More and more users are researching VOIP capability when purchasing a connection to the Internet or simply expanding their private intranet. VOIP can provide a cost-effective solution for companies that have locations in many disparate regions.

VOIP over satellite has become increasingly more popular for satellite users, and it is important to note several elements that must be considered when engineering a satellite network capable of handling VOIP:

  • Latency: Regardless of the satellite product, an approximate 280 msec of one-way propagation delay due to the location of the GeoStationary orbit and the speed of light, must be overcome.
  • Jitter: Packets transmitted at equal intervals from the transmitting gateway arrives at the receivieng gateway at irregular intervals. Excessive jitter has the effect of making speech choppy and difficult to understand. Packet "buffers" that hold incoming packets for a specified amount of time are used to counteract the effects of network fluctuations to create a smooth packet flow at the receiving end.
  • Packet Loss: Successful VOIP traffic must have very low Bit Error Rates (BER) to ensure low or no packet corruption or loss.
  • Compression Technologies: Understanding encoding schemes that have been standardized for voice is important for understanding true bandwidth requirements.
  • QoS and Traffic Prioritization: Packet switched networks are subject to congestion and congested networks can be very problematic for VOIP calls due to delayed, dropped or out-of-sequence packets. In order to guarantee delivery of VOIP traffic through congested links, it is vital to have QoS and prioritization.
  • Required Bandwidth per VOIP Call: To properly design a network, it is important to know the amount of bandwidth required per VOIP call, the number of concurrent calls, andthe duration of the call. The amount of bandwidth required per VOIP call would depend on the encoding standard used, header compression and payload size.

OptiStreams offers solutions that allow for simultaneous support of data, voice and video traffic. Unparalleled features and functionality ensure high-quality VOIP, even through congested networks.
