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.
EXAMPLES:
•
1,2,3,4,5,6,7,8,hunt=re;*;1
Lines 1 through 8 are participating (
The Trunk SUA will hunt to each specified line in the specified
order ( ). The call stays with a selected line until the
hunt=re
call is either answered, rejected, or cancelled by the caller
( ). The Trunk SUA replies 486 right away if no line is

NOTES:
•
The Trunk SUA rings only trunk lines (lines that are assigned
to a trunk group through the
Group
field).
• The Trunk SUA will not ring any standalone lines that are included in
the Contact List.
• The Trunk SUA will ring any trunk line that is included in the list, even if
it is not assigned to this particular trunk.

You can instruct the SPA8000 to hunt only the phones that are
