Number of IP Addresses per Call Leg Size
The table below defines the number of
call legs supported for a given number of IP Addresses assuming UDP ports 4,000 through 64,444 are configured for media port usage.
For
media resource allocation scenarios, the
requires a minimum of 10 IP addresses configured to support 150,000 call legs (one Primary IP address plus 9 alternate IP addresses in non-VLAN configuration).

|
For example, to use 100,000 call legs you must configure at least six (6) IP addresses because five IP addresses will only allow up to 96,000 call legs through the
.
The
supports configuring up to 14 alternate media addresses. For more details, see
Alternate Media IP Addresses Support.
Configuration Limits
The
supports a large number of configurable objects and is capable of supporting from a few very large customers to thousands of small customers. Important details about the provisioning system include:
- Interactive provisioning of configuration objects (such as commands typed at the CLI or entered in the EMA or EMS) does not affect call handling or capacity.
- Provisioning behavior does not depend on the number of existing entities. The addition of the 10,000th instance is roughly comparable to adding the 1st such instance.
Note |
---|
|
Bulk or non-interactive provisioning may affect call handling. Operations such as sourcing a CLI script with many configuration commands (or even a few commands affecting particularly large objects) should only be done during a maintenance window or at non-busy-hour intervals. |

The time required to add an object to an existing configuration is immaterial (It takes much longer to actually type the command or complete the EMA/EMS fields). However, bulk loading of a large configuration from the CLI may take a substantial amount of time.

|
See cautionary note above about the potential bulk configuration loading on call handling performance. |
While the
supports large limits on multiple types of configuration objects, a few typical usage scenarios exist. The length of time to bulk load a configuration depends on the size of the configuration. Consequently, four
profile classes are defined to give customers a rough idea for the bulk loading time relevant to their configuration:
- 1K profile – comprised of 1,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports, and Trunk Groups
- 4K profile – comprised of 4,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports, and Trunk Groups
- 4K/10K profile – comprised of 4,093 instances of IP Interfaces, 2,048 instances each of Zones, Address Contexts, IP Interface Groups, SIP Signaling Ports, 10,000 IP Peer, and 10,000 IP Trunks (see Note below).
- 4K/40K profile [SBC 7000 series only] – comprised of 4,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports; and 40,000 Trunk Groups

|
If both IPv4 and IPv6 are combined on every sipSigPort on an SBC 5200, the system limits the number of sipSigPorts to 1,980. |
Maximum CLI Load Times

For a system previously loaded with configuration, the start-up time also depends on the amount of configuration. The start-up time is considered the time from when the
application is started (by PM) to the time that the
is ready to accept calls.
Note that this start-up time is typically only relevant to standalone systems after an upgrade. For a HA system, the standby is activated to handle calls while the SBC is being started or restarted.
