SIP Trunking and Hunt Groups on the SPA8000 Contact List for a Trunk Group The hunting process for incoming calls is controlled by the Contact List. The Contact List specifies the lines to ring, the order in which to ring them, the duration to ring one line before trying another line, and the maximum period to hunt. Below, the syntax is described and examples are provided to help you to configure the Contact List for each trunk group. SYNTAX: line[,line[,line[...]]],hunt=hrule[,cfwd=target] • line: The line numbers (1 - 8), or a wildcard * or ? to represent all lines. NOTES: • The Trunk UA rings only trunk lines, that is, lines that are assigned to a trunk group through the Voice tab > Line page, Trunk Group field. The Trunk UA does not ring any standalone lines that are included in the Contact List. The Trunk UA rings any trunk line that is included in the list, even if it is not assigned to the particular trunk group for this Contact List. • 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 "Setting the Hunt Policy," on page 69. • hunt=hrule: The hunt order, ring interval, and maximum duration, in the following format: hunt=algo;interval;max • algo: The hunt order. - re: Restart. Hunting starts at the beginning of the list. If the first line does not answer within the specified interval (see below), the hunt proceeds through the lines in sequential order. - ne: Next. The Trunk UA determines the line that was chosen in the previous hunt, and hunting starts with the next line in the list. If that line does not answer within the specified interval (see below), the hunt proceeds through the lines in sequential order. - ra: Random order. The Trunk UA randomly chooses a line from the list. If the selected line does not answer within the specified interval (see below), the hunt proceeds randomly through the unchosen lines until each line is tried. - al: All. The Trunk UA rings all the lines at the same time. • interval: The number of seconds to wait for one line to answer, before choosing another line. If interval is *, the hunt is stopped at the first line that starts ringing, and rings the line until it answers, or the caller hangs up, or the line's ringer times out. • max: The maximum duration of the hunt, either in seconds or cycles. When this limit is reached, the call is rejected or is forwarded to the specified call forward number (see below). - If max is greater than interval, it represents the total time in seconds to hunt.
