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). |
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
