Signaling Protocol Identifier
Issue 3 April 2006 65
All IP telephones except the 4601 display the following text left-justified at the top of the
display:
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 telephone and the Message button LED on the faceplate flash 500
milliseconds on, 500 milliseconds off to indicate an entry is expected.
2. To change the SIG value, press *.
Depending on the current value, the next sequential valid SIG value is selected and
displayed as the protocol. For example, 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, all IP telephones except the
4601 display the following text left-justified at the top of the display:
The 4601 IP Telephone instead flashes both Message Waiting indicators 500 milliseconds
on, 500 milliseconds off to indicate an entry is expected.
3. Press the * button to terminate the procedure, or the # button to save the new value. If you
press the # button, all IP telephones except the 4601 display the following text:
The new value is saved. All phones except the 4601 display the following text left-justified at
the top of the display:
The 4601 IP Telephone instead flashes both Message Waiting indicators 500 milliseconds
on, 500 milliseconds off to indicate an entry is expected.
