Table : SBC Portfolio Key Features

Features

Description

General

  • Stand alone system
  • Optional HA (High Availability) system support
  • Includes an Embedded Routing Engine (ERE), performs DNS, ENUM lookups
  • Supports IPv4, IPv6, IPv4/IPv6 interworking, SIP, H.323, GW-GW, SSH, SNMP, NTP, RTP/RTCP, FTP, UDP, TCP, DNS, and ENUM.
  • Packet-to-packet call flows (B2B UA)
  • Extensive SIP signaling and session handling
  • Media relay and transcoding with pinhole control
  • Local storage
  • DoS protection
  • Crypto functions (IPsec, TLS, SRTP)
  • Integrated routing capabilities

Routing/ Policy

  • Embedded Routing Engine (ERE)
  • Standalone ePSX
  • Replica ePSX to an external PSX

Maximum number of call legs

1/2 of UDP media port rangeBased on number of IP addresses per interface and UDP media port rangeSee SBC SWe Performance Metrics

Two examples assuming 64,000 media port range:

  • SBC 5000 series number of call legs = 32,000
  • SBC 7000 series number of IP addresses = 6 / number of call legs = 110,000

See SBC 5000 and 7000 Series Provisioning Limits for details.

Multiple IP Addresses per interface

Maximum number varies based on server hardware where VM is deployed and VM vCPUs / memory configuration

For example, SBC 7000 4K/40K profile is comprised of:

  • 4,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports;
  • 40,000 Trunk Groups

See SBC 5000 and 7000 Series Provisioning Limits for additional provisioning details.
