Answer 2

Using Asterisk involves setting up and configuring the software to create custom communication solutions. Here’s a general overview:

Installation: Download and install Asterisk on a Linux-based system. You’ll need to install dependencies and compile the source code. This process includes commands like make install and make samples to set up configuration files2.

Configuration: Define dial plans, set up extensions, and configure SIP trunks for VoIP calls. Dial plans determine how calls are routed within the system2.

Integration: Connect Asterisk to VoIP providers or traditional telephony systems. You can use protocols like SIP, IAX, or H.3232.

Testing: Test the system with sample calls to ensure everything works smoothly2.

Customization: Use APIs like AGI (Asterisk Gateway Interface) or AMI (Asterisk Manager Interface) for advanced features and integrations2.
