14.4 Dynamic DNS
Dynamic DNS allows you to map your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you. SIP IP phones can
access the SIP server on the V500 using a domain name (for instance
myhost.dhs.org, where myhost is a name of your choice) that will never change
instead of using an IP address that changes each time you reconnect.
First of all, you need to have registered a dynamic DNS account with
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP
server that would still like to have a domain name. The Dynamic DNS service
provider will give you a password or key.
End Date Configure the day and time when Daylight Saving Time ends if you
selected Daylight Savings. The o'clock field uses the 24 hour
format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the last Sunday of
October. Each time zone in the United States stops using Daylight
Saving Time at 2 A.M. local time. So in the United States you would
select Last, Sunday, October and type 2 in the o'clock field.
Daylight Saving Time ends in the European Union on the last Sunday
of October. All of the time zones in the European Union stop using
Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So
in the European Union you would select Last, Sunday, October. The
time you type in the o'clock field depends on your time zone. In
Germany for instance, you would type 2 because Germany's time
zone is one hour ahead of GMT or UTC (GMT+1).
