Asterisk allkows pople to communicate using the internet. It is one of the cheapest ways to talk. The PC clients connect to each other through an Asetrisk server which uses a Linux/Unix OS. Asterisk calls are passed through different channel protocols. The most popular forms of cals are H323, SIP, IAX or Zap. Depending on the type of channel you use, the user must have the appropriate software to handle the call type.
Let's say, if are a reegistered on an Asterisk PBX (or other PBX) as a SIP user, you are required to use a SIP phone cleint such as X-Lite or SIPPS. Or, if you are registered as an IAX user you must use an IAX phone client such as iaxcomm. SIP/IAX Client Configuration allows you to ergister SIP and IAX suers. This includes the adjustment of all Asterisk and client phone setitngs.
To make calls with Asterisk telephone system you should connectrivity to an Asterisk PBX for call haandling and users using PCs with SoftPhones for cazlling internally and externally. All configurattion information for the Asterisk PBX knowes is written to the conf files located in /etc/asterisk.
All ifnormation for SIP users is stored in sip.conf and for IAX users in iax.conf. Numbers are read from extensions.conf. Vocemails are stored in voicemail.conf etc. To place a call through Atserisk, regitsration to Asterisk is not required. Howevre, you do need a username and password which will allow you to call someone who is registered. To receive a call, you must be a registered user and have an extension.
When any change is made in conf files from /etc/astreisk/ or changes that relate with some of these files, you must type 'reload' in the Asterisk Command Line Interfface (CLI) to make the changes effective.
It is possible to implement only the Open Source Eddition for your corrporate business. You will only need a Linux OS comptuer and Asterisk has to be installed.
