The following table illustrates the Latin 2 character set now used on the IP Phones.
Minimum Ringer Volume
To prevent the user from turning off the ringer, an Administrator can configure a parameter called “ringer volume mini-
mum” to set the minimum ringer volume level. When the minimum ringer level is reached while the user keeps pressing
the button, the level of sound does not change.
Locking IP Phone Keys
The IP phones allow you to lock or unlock programmable keys, softkeys, keypad keys, hard keys, cordless handset keys,
and expansion keys (for expansion modules). When key locking is enabled, the phone locks the key with the provisioned
local settings and prevents users from changing or configuring the key. In this case, the local settings (i.e. those configured
through the Web UI or [for the 6739i] the phone UI) take precedence over any key parameters defined in the configuration
files.
Note:
This minimum ringer volume does not affect the “silent” ring tone. When the silent ring tone is selected, no ringing will
be played by the phone
Configuration Files
For the specific parameter you can set in the configuration files, see Appendix A, the section, “Minimum Ringer Volume” on pageA-150.
Notes:
• If no settings are configured locally but the key type is defined in a configuration file, the phone will lock the respec-
tive key with the type defined in the configuration file along with any values associated with the additional key
parameters (e.g. for softkeys, “softkeyN label”, “softkeyN value”, “softkeyN line”, “softkeyN states”).
• Administrators also have the option of simply adding an exclamation mark (i.e. “!”) in front of the respective key
parameters to lock the keys to the values defined in the configuration files, overriding any locally configured settings
(see Locking Parameters in the Configuration File on page 2-15 for further details).
