Maximum number of call legs

1/2 of UDP media port range 1/2 of UDP media port range

Determined by:

  • number of IP addresses per interface
  • UDP media port range

 

(Refer to 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

(Refer to SBC Provisioning Limits for details).
