Enhanced Feature Keys
Customers replacing legacy telephony PBX or key system would like to get
equivalent functionality from their new VoIP telephony system. With SIP 3.0,
this feature allowed system administrators to program the speed-dials on their
phones to interact with the phone user to implement commonly used
functions such as “Call Park” in an intuitive fashion.
This capability applies to the SoundPoint IP 301,
320, 330, 430, 501, 550, 560,
601, 650, and 670phones. The enhanced feature key functionality is
implemented using Star Code sequences and SIP messaging.
The enhanced feature key definition language was defined to follow current
configuration file standards and to be extensible.
The particular Star Code sequence and the associated prompts displayed on
the SoundPoint IP phone for the enhanced feature are defined by macros.
These macros are case sensitive.
An enhanced feature key can be accessed from all instances where the
speed-dial is accessible, for example, unused line keys, speed-dial lists or
programmed to “hard” function keys.
This section provides detailed information on:
• Enhanced Feature Key Definition Language
• Macro Definition
• Configuration File Changes
• Useful Tips
• Examples
Enhanced Feature Key Definition Language
This section defines the additional fields to be entered into a configuration file
for controlling the enhanced feature key behavior. The definition language
follows the XML style notation. The following elements are part of the
definition language:
• <efk/>
• <efklist/>
• <efkprompt/>
• <version/>
• Special Characters
Note The Enhanced Feature Key feature from SIP 3.0 is compatible with Enhanced
Feature Key feature from SIP 3.1 . However, improvements have been made, and
Polycom recommends that existing configuration files be reviewed and updated.
