Refer to SBC Redundancy for details.

Maximum number of call legs

1/2 of UDP media port range1/2 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).

SIP Trunk Group profiles:

1K
4K
4K/10K
4K/40K

(Refer to SBC Provisioning Limits)

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

Refer to SBC Provisioning Limits for details.
