Description and More Information
Feature
Allows the phone to negotiate power using Link Level Endpoint Discovery Protocol
(LLDP) and Cisco Discovery Protocol (CDP).
Power Negotiation over LLDP
Submits phone logs or reports problems to an administrator.
Problem Reporting Tool
You can assign features, such as New Call, Call Back, and Forward All to line buttons.
Programmable Feature Buttons
Allows users to call the most recently dialed phone number by pressing a button or the
Redial softkey.
Redial
Allows a service provider to customize the phone remotely. There is no need for either
the service provider to physically touch the phone or a user to configure the phone. The
service provider can work with a sales engineer at the time of ordering to set this up.
Remote Customization (RC)
Identifies ring type used for a line when a phone has another active call.
Ringtone Setting
Identifies the caller name using the incoming or outgoing call number. You must configure
either the LDAP Directory or the XML directory. You can enable or disable the reverse
name lookup using the phone administration web page.
Reverse Name Lookup
Ensures that held calls are not dropped by the gateway. The gateway checks the status
of the RTCP port to determine if a call is active or not. By keeping the phone port open,
the gateway will not end held calls.
RTCP Hold For SIP
Enables administrators to quickly and easily gather debug information from phones.
This feature uses SSH to remotely access each IP phone. SSH must be enabled on each
phone for this feature to function.
Serviceability for SIP Endpoints
Allows a user with multiple phones to share the same phone number or allows a user to
share a phone number with a coworker.
Shared Line
The phones can display both the calling ID and calling number for incoming calls. The
IP phone LCD display size limits the length of the calling ID and the calling number that
display.
The Show Calling ID and Calling Number feature applies to the incoming call alert only
and does not change the function of the Call Forward and Hunt Group features.
See “Caller ID” in this table.
Show Calling ID and Calling Number
Displays the time duration of placed and received calls in the Call History details.
If the duration is greater than or equal to one hour, the time is displayed in the Hour,
Minute, Second (HH:MM:SS) format.
If the duration is less than one hour, the time is displayed in the Minute, Second (MM:SS)
format.
If the duration is less than one minute, the time is displayed in the Second (SS) format.
Show Duration for Call History

Ignore
softkey or by pressing the
volume button down.
