SBO4VOIP guarantees voice quality by ensuring that VoIP traffic is efficiently and effectively prioritised at byte level, reducing jitter and preventing call break-up.
  • Until now suppliers of IP PBX solutions or Hosted VoIP services have found themselves constrained by the cost of SDSL or leased lines for higher capacity connectivity or the limited capacity of lower cost ADSL circuits.
  • Deployed between your customers and your hosted VoIP PBX, or over a SIP trunk connection, our technology reduces bandwidth requirement so effectively that a single 256K ADSL circuit can carry 32 G729 calls with no loss of call quality.
  • For your customers that already have leased lines and would like to use these for VoIP traffic, SBO4VOIP provides a method of maximising existing investment by reducing the amount of bandwidth required for the added VoIP traffic, and by implementing SBO4VOIP QoS over the circuit, can guarantee the quality of the voice calls.
  • In SIP Trunking applications the use of SBO4VOIP technology can allow an existing PRI to be replaced with a single 256K ADSL circuit. Gone are the days of high cost leased lines or SDSL circuits, VoIP replacement of PRI circuits becomes a truly cost effective and viable alternative and allows a ‘peace of mind’ failover option via Basic Rate ISDN data circuits
  • Installing SBO4VOIP within your network to provide higher call capacity and SBO4VOIP QoS could mean the difference between cost effective, guaranteed quality calls and a system that works some of the time – but never during that crucial sales call.
  • Through its ability to effectively use ADSL links to carry higher levels of VoIP traffic SBO4VOIP enabled circuits can normally be installed much quicker than leased line or SDSL circuits and will show significant cost savings.
  • By working with an ISP that has a SBO enabled infrastructure SBO4VOIP can even be cost effectively deployed for remote workers at SOHO locations wanting to use VoIP telephony over ADSL.

To deploy SBO4VOIP Technology, a minimum of one SBO4VOIP server and either a SBO4VOIP router or SBO4VOIP enabled ADSL modem for the customer, is required.

SBO4VOIP finally delivers VoIP without compromise.

When used within your network SBO4VOIP can reduce the bandwidth required to carry VoIP traffic by up to 80%.

  • SBO4VOIP is an IP tunnelling protocol specifically designed to provide true Quality of Service for VoIP over ADSL broadband circuits.
  • SBO4VOIP provides not only byte level QoS but also RTP header compression to allow your customers to run more VoIP calls with unprecedented quality over ADSL circuits carrying both voice and data.
  • SBO4VOIP server deployed in your network allow you to offer a chargeable premium service that can guarantee call quality and in SIP trunking applications allows you to offer 32 channels of G.729 calls over a 256/512K ADSL circuit.
  • SBO4VOIP Servers allow you to licence the service that you offer on a “per channel” basis so that you can differentiate between a residential customer that has a single VoIP connection and those customers that require 28 channels to replace a traditional PRI.
  • SBO4VOIP enabling your network allows you to offer service quality guarantees to the growing number of VoIP service providers who are looking for high quality broadband connections for their customers.
  • For ISPs wanting to offer their own VoIP service you no longer need to consider using strategies like multiple PVCs and dedicating bandwidth as SBO4VOIP dynamically allocates bandwidth as it is required and provides byte level QoS over the circuit.
  • SBO4VOIP can also allow you to offer higher bandwidth, higher quality codecs without having to sacrifice too much bandwidth.
  • For the customer SBO4VOIP can be integrated into a number of existing ADSL modems and broadband routers so that the cost of implementation is low.
  • By using SBO4VOIP, ISPs can now offer an alternative to traditional leased lines for VoIP applications. Using uncontended ADSL tails and routing within a SBO4VOIP enabled network it is possible to offer a service that competes directly with SDSL or leased lines but is quicker to install and more cost effective.
  • Because SBO4VOIP provides true QoS in both directions it is Ideal for home workers who need to use VoIP telephony over ADSL and still need to access company information over the Internet at the same time.
  • A single SBO4VOIP server can pay for itself in less than 4 months and allow an ISP to generate significant extra revenue


To deploy SBO4VOIP Technology, a minimum of one SBO4VOIP server and either a SBO4VOIP router or SBO4VOIP enabled ADSL modem for the customer, is required.

  • Deployed between your customers and your hosted VoIP PABX, or over a SIP trunk connection, SBO4VOIP technology reduces bandwidth requirement so effectively that a single 256K ADSL circuit can carry 28 G729 calls with no loss of call quality.
  • SBO4VOIP guarantees voice quality by ensuring that VoIP traffic is efficiently and effectively prioritised at byte level, reducing jitter and preventing call break-up.
  • In SIP Trunking applications the use of SBO4VOIP technology can allow an existing PRI to be replaced with a single 256K ADSL circuit. VoIP replacement of PRI circuits becomes a truly cost effective and viable alternative to traditional ISDN30 and SBO4VOIP allows a “peace of mind” redundancy option via Basic Rate ISDN data circuits.
  • For organisations that already have leased lines between sites and would like to use these for VoIP traffic, SBO4VOIP provides a method of maximizing existing investment by reducing the amount of bandwidth required for the added VoIP traffic, and by implementing SBO4VOIP QoS over the circuit, can guarantee the quality of the voice calls.
  • Installing SBO4VOIP within a customer’s existing infrastructure alongside a new VoIP enabled PABX could mean the difference between cost effective, guaranteed quality calls and a system that works most of the time.
  • Where a single new VoIP enabled PBX is being used to replace older multiple PABX installations, and there are no established data links between sites, SBO4VOIP allows the use of lower bandwidth links or more cost effective technologies.
  • Through its ability to effectively use ADSL links to carry VoIP traffic, SBO4VOIP enabled point to point links can normally be installed much quicker than leased line or SDSL circuits and will show significant cost savings, even in year one. Over the life of a VoIP PBX, SBO4VOIP could save your customer tens of thousands of dollars in expensive leased line circuit costs.
  • SBO4VOIP can even be deployed between a company and its employees working from SOHO locations and using VoIP telephony over ADSL. Unlike the QoS options found on some ADSL modems a SBO4VOIP enabled ADSL modem works with a SBO4VOIP server device to control data both to and from the remote site ensuring VoIP data is efficiently and effectively prioritised, guaranteeing voice call quality while the SBO4VOIP IP VPN continues to allow online access to company information.

  • For multi-site locations, a Point to Point solution is the easiest way to deploy SBO4VOIP.
  • Deployed as a Point to Point solution in your enterprise SBO4VOIP technology enables your iPABX to truly function as intended.
  • SBO4VOIP VPN QoS and compression technology guarantees voice quality by ensuring that VoIP traffic is efficiently and effectively prioritised at byte level within your network. Using SBO4VOIP technology also means that you no longer need as much expensive bandwidth to carry VoIP traffic between your VoIP enabled PABX and remote office locations.
  • SBO4VOIP virtually eliminates packet overhead, reducing the bandwidth required by a codec to its original size. In fact SBO4VOIP is so efficient that it can allow a 256K data link to carry 32 simultaneous G729 calls.
  • In SIP Trunking applications the use of SBO4VOIP technology can allow an existing PRI to be replaced with a single 256K ADSL circuit. Gone are the days of high cost leased lines or SDSL circuits, VoIP replacement of PRI circuits becomes a truly cost effective and viable alternative to traditional ISDN30 and SBO4VOIP allows a ‘peace of mind’ failover option via Basic Rate ISDN data circuits.
