Site-Specific Option Number Setting
!
CAUTION:
CAUTION: Do not perform this procedure if you are using static addressing. Perform this
procedure only if you are using DHCP and the LAN administrator instructs you to
do this.
Use the following procedure to set the Site-Specific Option Number (SSON).
1. While the telephone is on-hook and idle, press the following sequence of keys on the
faceplate of the telephone:
Mute 7 7 6 6 # (Mute S S O N #)
Note:
Note: Press the Mute button momentarily. Do not press this button while pressing other
keys/buttons. The 4630/4630SW IP Telephones and the 4690 IP Conference
Telephone do not have a dedicated Hold button. For all other 4600 Series IP
Telephones, pressing the Hold button instead of the Mute button also works.
All IP telephones except the 4601 display the following text left-justified at the top of the
display:
where ddd is the value of SSON.
Because it does not have a display, the 4601 IP Telephone’s Call Appearance Line
indicators wink out the current SSON value. Call Appearance Line a represents the SSON’s
first digit. Call Appearance Line b represents the SSON’s second digit, and Call
Appearance Line a represents the SSON’s third digit. For each digit, the applicable indicator
winks the number of times represented by the current SSON value 600 milliseconds on, 200
milliseconds off. An 1800 millisecond pause occurs before changing indicators. If the
current value is zero, the appropriate Call Appearance Line indicator flutters five times 50
milliseconds on, 50 milliseconds off instead of winking.
After the 4601 “displays” the current SSON, the Message Waiting indicator at the top of the
telephone and the Message button LED on the faceplate flash 500 milliseconds on, 500
milliseconds off to indicate an entry is expected.
