Works on Any Internet (DSL / ADSL / 3G / Sat etc)

Frequently Asked Questions

Any questions you have about SBO should be answered in the following FAQ’s. Contact us if you cannot find what you a looking for.

Q: What is SBO?
A: SBO stands for: Solution4VOIP’s Bandwidth Optimizer. SBO Technology overcomes the problems with VoIP over ADSL by treating voice data as priority traffic.

Q: How does SBO work?
A: We have a much more detailed explanation on the How SBO Works page but in a nutshell this is how SBO works:
SBO analyses voice data packets over a network and strips out anything that is not essential, only data essential to the delivery of voice (data) remains. SBO also gives voice data precedence over other types of data ensuring that call quality is always maintained.

Q: Who is SBO For?
A: SBO is perfect for any size of business or organisation that uses VoIP based telephony. SBO is also a good fit for any business looking to make the move to a VoIP based system.
Service Providers will also benefit significantly from SBO by deploying it over their networks to benefit their own VoIP service.

Q: Is SBO Hardware or Software?
A: Both really. SBO can be installed on some existing routing hardware (Netgear, Mikrotik, TPLink Routers) however there may be some limits to functionality when loading SBO onto OEM equipment (check with us if you have an queries). At the head-end or data centre then the appropriate device should be selected to run the SBO provisioning and management software.

All SBO hardware supports:

Full router functionality such as policy routing, BGP, stateful firewall, etc
Hardware failover using VRRP
Link bonding and failover, call access control, statistics generation, etc

Q: What Does SBO Cost?
A: This depends on how your ISP or distributor has packaged SBO check with your approved reseller or distributor or click here to check our available plans.

Q: How many simultaneous VoIP calls can SBO carry?
A: The only limiting factor on how many VoIP call SBO can carry is bandwidth. The first call SBO processes has an overhead of 38.1Kb with every additional call adding 8.6Kb to the load. So a broadband connection with a 2Mbps (2048Kbps) upload speed would be able to carry 234 simultaneous VoIP calls without loss of call quality and allowing other data to flow over the connection.

SBO Equation

To work out your anticipated number of concurrent calls on your available bandwidth simply take the available bandwidth (upstream) subtract 38.1 and then divide by 8.6. This will give you a rough guide on the number of concurrent calls you would get with this available bandwidth. Note however bandwidth availability and quality tends to be sporadic in South Africa so take your worst case available and use that number.

Q: Can SBO reduce my costs?
A: Yes, assuming that you are already running a VoIP system, SBO will reduce your VoIP bandwidth requirements.

Q: Does SBO support line bonding?
A: One of the added benefits of SBO is that is does support line bonding. Despite being developed to carry VoIP calls SBO also has the benefit of being able to create VPN tunnels with multiple ADSL lines, which in effect is bonding. Unlike the Cisco based solution using SBO to bond ADSL has relatively low setup costs. Bonding with SBO requires a router for each ADSL line and a single piece of SBO enabled hardware to handle the bonding process.
