What is the Asterisk SIP Settings Module used for?
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.
