Trunk Group page (SPA8000) Contact List (continued) NOTES: • The Trunk SUA rings only trunk lines (lines that are assigned to a trunk group through the Voice tab > Line page, Trunk 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 on-hook, through the Voice tab > SIP page, Trunking Parameters section, Hunt Policy field. See "Trunking Parameters section (SPA8000)," on page 109. Voice tab > Trunk Group page > Dial Plan section Field Dial Plan Description Dial plan script for this trunk. NOTE: The trunk SUA will also apply the Trunk Dial Plan on the number before sending out INVITE to the ITSP. This Trunk Dial Plan typically is redundant since the trunk should trust the number sent by the Line SUA. By default the trunk dial plan allows any non-empty number: ([*#0-9A-D][*#09A-D].)
