Local Administrative Options

Signaling Protocol Identifier

Use the following procedure to set or change the Signaling Protocol Identifier. A valid SIG Protocol Identifier is either 0 (default), 1 (H.323), or 2 (SIP).

Note:

Perform this procedure only if the LAN Administrator instructs you to do so.

1.While the phone is on-hook and idle, press the following sequence of keys on the faceplate of the telephone:

Mute 7 4 4 (Mute S I G)

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:

SIG=protocol *=change #=OK

where protocol is the telephone’s signaling protocol (H.323, SIP, or default) corresponding to the numeric identifier (1, 2, or 0).

Because it does not have a display, the 4601 IP Telephone’s Call Appearance Line a’s indicator winks out the current SIG value 600 milliseconds on, 200 milliseconds off. One wink represents H.323 and two winks represent SIP. If the current value is zero (the default), Call Appearance Line a’s indicator flutters five times 50 milliseconds on, 50 milliseconds off instead of winking. After the 4601 “displays” the current SIG value, the Message Waiting indicator at the top of the phone and the Message button LED on the faceplate flash 500 milliseconds on, 500 milliseconds off to indicate an entry is expected.
