Standards implementation

  • SIP (Session Initiation Protocol) - RFC- 3261for trunks only
  • IP ToS: Applied to RTP voice packets by default
  • 802.1p/Q: Automatically applied for RSGM and devices in Remote mode
  • IPSec: Two encryption algorithms (DES/3DES) & two hash algorithms (MD5/SHA-1) are supported
  • STUN (Simple Traversal of UDP through NAT): Based on RFC3489, but modified toefficiently operate for Vodavi Telenium™ IP communications
  • PPPoE: Supported by phones and RSGM
  • DHCP: Phones support DHCP client configuration in Remote mode RSGM supports DHCP client for WAN interface, and DHCP server (up to 50 internal clients) on its LAN interface
  • NAPT: Phones supported behind NAT/NAPT devices Router in RSGM provides NAT/NAPT support so that all clients can use private addressing
  • HTTP: All devices except SHUB8 and POE8 have HTTP-based administration or upgrade
    capability
