Key features

Flexible deployment

• Supports both local and remote PBXs
• Operates over Satellite links
• Support for multiple voice protocols

Optimising Bandwidth & Reducing Jitter

• ‘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 

Improving Call Reliability and Security

• 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

Management and ease of use

• 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
