The Asterisk SIP Settings Module is used to configure the default settings used for SIP calls. Since most VOIP calls are sent using SIP, these settings can be very important to the operation of your PBX. Because this module sets the default settings, most of these settings can be overriden for a particular extension in the Extensions Module or for a particular trunk in the Trunks Module.
How Do I Get to the Asterisk SIP Settings Module?
To access the Asterisk SIP Settings Module in FreePBX 2.10 and later, access the graphical user interface using a web browser. Click on the "Settings" pull down menu at the top and then select "Asterisk SIP Settings".
What Do Each of the Asterisk SIP Settings Options Mean?
You can get a general description of what each option does by placing your mouse on the question mark to the right of the option, and a tooltip will appear that explains the option.
