This test is an end to end VoIP setup with calls forwarded by an Asterisk in the middle where the rate of the call establishment is measured. Calls can be generated and terminated by the abacus system.
To deploy Enterprise-Class Asterisk solutions you need
Measure performances and perform optimization
Test Again ;)
Certify your performances to your customers
With the simple (but important) examples we can learn a some important thinks.
Conclusion (2) Identify your deployment target Study the competitor's performances in order to have a reference Spend time to analyse and optimize your dial plan Study your system (OS & Applications) in order to optimize the configuration parameters
Conclusion (3) A simple example: when you grow the number of the concurrent calls you get the following error in Asterisk: ERROR rtp.c: Unable to allocate socket: Too many open files To solve the trouble you need increase the number of Operating System Open Files. In GnuLinux you need add the following command in startup Asterisk script: ulimit -c unlimited
