Quality of Service (QoS)
It is possible to view the quality of service statistics of the connection for
the last 10 calls via the web interface. The statistics shows for example
the delay, jitter and number of lost packets. See maintenance instruc-
tions for
IP TELEPHONE DBC 42X
.
7.32 Language
handling
The language file will be stored on the SW server and is fetched from the
server to the phone at start up of the phone. The end user may choose
a language other than English using the language menu in
Settings
mode.
It is possible for the system administrator to change text strings e.g. for
Absence reasons. See the description for
LANGUAGE FILE FOR DBC

Setting Time and Date
Time and date can be set using the following alternatives:
•
WAP messages. For PBX's supporting WAP, the time in the IP
phone is updated automatically as soon as the phone is registered
towards the PBX.
•
SNTP (Simple Network Time Protocol). The time in the phone can
be set via SNTP, as described below. This method must also be
used if security is enabled (with validation of the server certificate)
in the phones and in the system.
If the SNTP server is enabled and defined in the configuration file, the
phone will take the time from the SNTP server.
7.33.1
Simple Network Time Protocol
When SNTP is available in the LAN, the time and date in the phone are
updated automatically when the phone is started and is verified periodi-
cally. If SNTP is used, the IP address and the Time zone will be set in
the configuration file, see
Configuration File for DBC 44X and DBC 43X
.
If the LAN does not have SNTP or NTP available, a server with SNTP
software has to be initiated.
