A human engine has a torque curve similar to that of a steam engine, more or less, which is to say that it is flat until a certain critical rpm, at which point it begins to drop off, because the energy used in accelerating and decelerating massy components (legs) begins to take up all the energy produced.
Asterisk (PBX) Asterisk is a software implementation of a telephone private branch exchange (PBX); it allows attached telephones to make calls to one another, and to connect to other telephone services, such as the public switched telephone network (PSTN) and Voice over Internet Protocol (VoIP) services.
This Asterisk course is designed for all skill levels to compile and install Asterisk from source on a CentOS Linux server. No prior Linux or Asterisk experience is required. I work in a lab environment to show you step by step how to get Asterisk running and configure it.
