Contact List
Contact List
(continued)
This parameter determines which trunk lines to ring on an
incoming call.
When an incoming call is detected by the Trunk SUA (SIP
User Agent), the SUA first checks if there is capacity to
handle the call. If not, the SUA rejects the call with a 486
response. If there is spare capacity, the SUA consults the
Contact List to determine which lines to ring (that is, for the
proxy to send SIP INVITE to), and starts "hunting."
The Contact List specifies the lines, the hunt method, and
other options.

call is either answered, rejected, or cancelled by the caller
