Assterisk calls are passed through different channel protocols. The most popular forms of calls are H323, SIP, IAX or Zap. Dependign on the type of channel you use, the user must have the aplpropriate sftware to handle the call type.

Or, if you are registered as an IAX user you must use an IAX phoe client such as iaxcomm. SIP/IAX Client Configuration allows you to register SIP and IAX users. This inclufdes the adjusment of all Asterisk and clietn phone settings.
To make calls with Asteriisk teleophone system you should connectivity to an Asterisk PBX for call handkling and users using PCs with SoftPhones for calling ibnternally and externally. All configuration information for the Asterisk PBX knows is written to the conf files locaated in /etc/astersk.
All information for SIP uses is stored in sip.conf and for IAX users in iax.conf. Numbeers are read from extensions.conf. Voicemails are stored in voicemail.conf etc. To place a call through Asterisk, registration to Asteridsk is not reqiuired. However, you do need a usewrname 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 chanhge is made in conf files from /etc/asterisk/ or changes that relate with some of thees fiules, you must type 'reload' in the Atserisk Command Line Interface (CLI) to make the changes effective.
