TDMoIP with Voice Compression

Compress 16xT1s over IP or 1xT1. Use 60% less bandwidth than VoIP.



  • Extend up to 16 T1 circuits over IP or a single T1 and slash your bandwidth costs.
  • Maintain voice quality while reducing bandwidth requirements per channel as low as 4 kbps.
  • Uses 60% less bandwidth than VoIP.
  • Starts at only $3000 for a single compressed T1 voice link, guaranteeing you a positive ROI within months.
  • Single compression cycle on multi-hop trunks improves voice quality.
  • Transparent to all signaling protocols.
  • Modular solution allows you to expand as your need for bandwidth grows. Select up to 4 hot swappable voice compression modules each handling 2 or 4 T1 circuits.
  • Optional dual hot swappable power supplies for increased redundancy.
  • Dynamic bandwidth allocation, voice activity detection (VAD) and silence suppression mechanisms reduce bandwidth requirements.
  • QoS maintained through VLAN tagging or labeling IP level priority (ToS).
  • SNMP facilitates remote management.
