SBC SWe Lite Call Performance
SBC SWe Lite Performance Numbers
Setup | ||
|---|---|---|
Side 1 Protocol | Max Sessions/Channels | Call Rate |
SIP | 100 Sessions (100 SIP calls, each with two SIP channels) | 10 cps |
Call Capacity Limitation with Additional Logging
Call capacity is limited to X calls per second when Info level logging is enabled. Additional logging verbosity reduces the call capacity.
Although the call setup rate is 10 calls per second, if Call Admission Control (CAC) is enabled, calls over the rate limit will be rejected with the message 480 Temporary Not Available.

SBC SWe Lite Capacity

SBC SWe Lite Maximum Configuration Values
Feature | Maximum supported |
|---|---|
Number of Signaling Groups | 100 |
Cumulative number of channels across all the Signaling Groups | 600 |
Call Route Entries (all Call Route Tables combined) | 1,000 |
| Static Routes | 1,024 |
Registrar Table entries | 600 |
Registrant Table entries | 600 |
Transformation Table entries | 1,000 |
Media Profiles entries | 20 |
| SIP ↔ SIP Calls | 100 |
| Simultaneous Calls | 100 |
| Callback Number Tables | 80 |
| Callback Numbers (in Callback Numbers List) | 16 |
Call Forking
The
Unable to show "metadata-from": No such page "_space_variables"
supports local call forking up to eight separate destinations. Additionally, the Unable to show "metadata-from": No such page "_space_variables"
supports up to 20 early dialog responses and 20 calls forked downstream.SIP Licensing
Any SIP ↔ SIP call consumes a single SIP session, for the life of the call, within the pool of SIP sessions that have been activated through a license submission..
Exceptions
No SIP session is consumed from the pool of licensed SIP sessions when a SIP ↔ SIP call has on any one leg any one of the following devices:
- SBC Edge
- VX
- Tenor
You do not need to purchase a license for these SIP ↔ SIP calls because the
Unable to show "metadata-from": No such page "_space_variables"
will make accommodations.Burst Behavior
If multiple calls arrive simultaneously, the
Unable to show "metadata-from": No such page "_space_variables"
will service the calls until it reaches a CPU usage threshold (~XX%).- When the threshold is reached the Unable to show "metadata-from": No such page "_space_variables"will reject calls until it reaches a "safe" level (~XX% CPU usage).
- When the "safe" level is reached, the Unable to show "metadata-from": No such page "_space_variables"will begin accepting new calls.
Turning on the CAC or logs could exacerbate this issue.
