Hello. We are having this issues with time blinking on our Polycom IP 331 phones. We had an Asterisk server that broke down, so we have to build another one from scratch. Several configurations weere taken from previous server that worked properly. We managed for the clock from server and harware clock are syncronized, and it is important to mention that we live in Venezuela, South America, so we need for our server to get the correct hour and display it on the Polycom phones.
That is what we have done so far:
1-This what I have on “nano /etc/ntp.conf”, there are some server that we have after “#”
For more information about this file, see the man pages
ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).
Permit time synchronization with our time source, but do not
permit the source to query or modify the service on this system.
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
Permit all access over the loopback interface. This could
be tightened as well, but to do so would effect some of
the administrative functions.
Hosts on local network are less restricted.
#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
Use public servers from the pool.ntp.org project.
Please consider joining the pool (http://www.pool.ntp.org/join.html).

Undisciplined Local Clock. This is a fake driver intended for backup
and when no outside source of synchronized time is available.

Drift file. Put this in a directory which the daemon can write to.
No symbolic links allowed, either, since the daemon updates the file
Enable public key cryptography.
Key file containing the keys and key identifiers used when operating
with symmetric key cryptography.
Specify the key identifiers which are trusted.

Specify the key identifier to use with the ntpdc utility.
Specify the key identifier to use with the ntpq utility.
Enable writing of statistics records.

Disable the monitoring facility to prevent amplification attacks using ntpdc
monlist command when default restrict does not include the noquery flag. See
CVE-2013-5211 for more details.
Note: Monitoring will not be disabled with the limited restriction flag.
2-Now on “nano /etc/asterisk/indicacionts.conf” I have this (what is after “#” is what was before)

3-On “nano /etc/asterisk/extensions_additional.conf”, we added these lines
TIMEFORMAT = kM
TONEZONE = ve
4-We ran the command “ln -sf /usr/share/zoneinfo/America/Caracas /etc/localtime”
5-Checking “nano /etc/php.ini” on we wrote "date.timezone = America/Caracas
What more should we need to do in order for our phones to get the right time on the display?.
Thanks in advance.
