CONFIGURING THE IP250D
3.4.3 VLAN Settings
To enable VLAN for SIP and audio traffic, set the VLAN TAG and PRIORITY TAG. Press
SAVE VOIP VLAN SETTINGS to save the VLAN settings. Reset the unit to have the new
settings take effect.
3.5 CODEC CONFIGURATION
This page is available for configuring the audio CODEC parameters. Enter which codecs
are to be supported. For some protocols (e.g. SIP), the G711U and G711A protocols are
always supported by default. For MGCP, it is possible to remove these codecs from the
device’s list of supported "capabilities".
Select the appropriate complex codec if it is desired. Select the packetization period to be
used. For MGCP, a range of packetizations may be provided for each codec (to be
advertised in the device’s "capabilities" set.)
Finally, select whether silence suppression is to be supported for each codec. Press SAVE
CODEC SETTINGS to save the new codec parameters. These settings will only take effect
when the device is rebooted.
3.6 SYSTEM CONFIGURATION
This main menu option provides subpages to configure the device’s security and
localization settings.
3.6.1 Security Settings
This sub-page allows an administrator to configure the device with an access password.
Enter the password and confirm by reentering it. Press SAVE SECURITY SETTINGS to apply
the password protection. Effective immediately, the password will be required whenever
anyone wishes to access the device’s configuration web pages.
3.6.2 Localization Settings
This sub-page only applies to devices running a VoIP protocol, and is used to configure
the localization settings of the device. Enter the country (certain media hub devices
require this information in order to communicate with analog phones which follow dif-
ferent international standards.) If you wish for the device to automatically obtain the
time via NTP, enter the NTP server address for the network (if this address is left blank, a
default public NTP server will be used, if accessible). Select the time zone, and whether or
not to adjust for daylight savings. Press SAVE LOCALIZATION SETTINGS to save the new
values. These settings will only take effect when the device is rebooted.
