## Signaling Protocol Identifier

NOTE: This procedure is provided for future use only, and is not currently applicable to Release 1.0.

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 telephone 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 telephone displays 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).

1. To change the SIG value, press *.

Depending on the current value, the next sequential valid SIG value is selected and displayed as the protocol. I.e., if the current value is SIP (2), pressing * changes the value to 0 (default). If the current value is H.323 (1), pressing * changes the value to 2 (SIP).

If a value different from the current Group value is entered, the telephone displays the following text left-justified at the top of the display:

Save new value? *=no #=yes

1. Press the * button to terminate the procedure, or the # button to save the new value. If you press the # button, the telephone displays the following text:

New value being saved

The new value is saved. All telephones display the following text left-justified at the top of the display:

Restart phone? *=no #=yes

1. Press the * (asterisk) key to terminate the procedure without restarting the telephone.

Press the # (pound) key to restart the telephone.

The remainder of this procedure depends on the status of the boot and application files.
