InnoMedia Enterprise Session Border Controllers (ESBCs) for SIP Trunking – Features and Benefits

  • B2BUA for signaling normalization – Reduces SIP interoperability hurdles
  • Media transcoding for media normalization – Codec transcoding, DTMF translation between RFC2833 and in-band, Fax transcoding between T.38 and G.711 fallback
  • Carrier-grade monitoring utilities – VoIP metrics, SIP End-point Test Agent (SETA), ladder diagrams and WAN/LAN PCAP call flow trace captures
  • SIP Header Manipulation Rules (SHMR) for in-field manipulation
  • IMS ready and SIPConnect compliant
  • QoS management for both Ethernet and cable interfaces
  • VoIP call quality telemetry with RTCP-XR and end-of-call syslog reporting
  • Highly Integrated with internal battery and optional DOCSIS 2.0/3.0 cable modem

As part of InnoMedia’s comprehensive business voice service solutions, InnoMedia’s highly manageable ESBC product family provides complete B2BUA functions for signaling normalization, and transcoding for codec/fax/DTMF media translation. These IMS-ready and SIPConnect-compliant ESBCs are ideal for service providers looking for scalable SIP trunking deployment.
