VOIPbox

voice over ip acceleration appliance

Key features

‘Super packets’
- Only one set of IP and UDP headers is needed for each ‘super-packet’ sent
- Unnecessary information for each voice channel is not transmitted.
- The cell padding effect, present on broadband networks, is eliminated
- The amount of data sent in a ‘super-packet’ can be as little as a single byte, meaning a class of traffic can be allocated 50 bytes per second (on a 256k link) and still function.
- Bandwidth consumption is lower and far fewer packets per second are sent across the WAN, reducing load on routers and network congestion
Header compression
The bandwidth budget is reduced to that of the compression format used. A G.729 call only uses 8Kbit/s over the link
Packet prediction
VOIPBOX predicts when voice packets need to be sent. This helps reduce VoIP jitter almost to zero, no matter how much data is being sent or how large the MTU of the connection

Backup links
Built in switch over to secondary IP connectivity enables resilient services to be deployed. Can be activated without losing calls in progress
Line bonding
ADSL lines can be bonded providing more bandwidth and resilience allowing the loss of a line without losing calls in progress
Private networks
VOIPBOX enabled sites can be joined together to form private networks, which means that security is easier to control

Web administration via secure SSL web interface
Shared management for multiple administrators via RADIUS authentication
Operating system runs from read only CompactFlash.
Simple upgrade facility: performance, feature and security updates packaged as a single file
SNMP support allows the box to be monitored by standard networking tools
Supports Syslog output to remote Syslog server
Backup and restore
