VoIP Performance: Maximum Number of Calls per Second (not exceeding 75-percent CPU)
Notes:
1.
All results represent G.729A or G.711 (20-ms packetization) switched H.323 calls with VAD turned off.
2.
The call success rate (CSR) of all tests is 98 to 100 percent.
3.
Call duration of tests is 180 seconds except for calls-per-second rate testing, where the duration is shorter.
The test release is Cisco IOS Software Release 15.0.1M. This document contains general numbers as a guide to
the approximate performance of the unified communications routers. The numbers are extrapolated from a large
number of disparate tests, test conditions, and traffic patterns. Several nontesting factors have also been
accounted for. Therefore, actual test results will vary, and we encourage you to do proof-of-concept testing for
more specific performance numbers for a specific scenario, traffic pattern, or release.
End-of-Sale Platforms
Tables 8 and 9 provide system requirements for the end-of-sale unified communications routers.
