In the first article on Asterisk, we have seen the Asterisk installation steps and on the environment setup. In this article, we have give the configuration settings for two files iax.conf and extensions.conf which will be used to direct/receive calls from/to iax2 soft clients

File: iax.conf

After saving these two files, start up asterisk. $ asterisk -vvvvgc

The above command will open the asterisk CLI - Command Line Interface
