call switch is pressed and will continue to flash until

SETUP
The VIP-4122-A12 is programmed at the factory to
acquire an IP address using Dynamic Host
Configuration Protocol (DHCP). If DHCP is not
available, it will revert to the IP address of
192.168.6.207 after 3 minutes.
In addition to the IP address, the clock will also try
to acquire all the information needed to synchronize
time from the DHCP Scope. If the DHCP Scope
Options noted below are correctly configured, the
clock will be able to acquire the correct time without
further programming.
•
Option 42, NTP Server IP Address.
•
Option 100, POSIX Time Zone, example:
"EST5EDT4,M3.2.0/02:00,M11.1.0/2:00".
This is the preferred option and works for
any area of the world.
•
Option 101, Time Zone Name, example:
"America/New_York". This option is only
supported for North America time zones.
Each of these options from the DHCP scope can be
overridden by manually programming the desired
value using the Valcom VIP-102B IP Solutions
Setup Tool. If not using DHCP for IP address
assignment, all the Time settings will be configured
using the Setup Tool.
