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
