Voice autoinformer of date and time, pleasant female voice, Russian, based on asterisk? Easy
On the eve of the weekend, there is nothing to occupy, since according to the regulations grandiose settings are not allowed? On an old, abandoned server, asterisk dusty? Is the subscriber nothing to test the telephone line? For those who have no one to talk to and for those who are lost in time .
In this publication, we will focus on the case of ordinal numbers, since the spoken text must be connected and not cut the ear. Try to achieve the following pronunciation:

For simplicity and transparency of implementation, we will not use AGI and ask the iron lady to tell us the date and time, by and large, after working only with dialplan and say.conf. And if your asterisk still does not speak Russian - it does not matter, we will teach it. To whom it became interesting, welcome to habrakat.
I think you should not even mention that your server should know the exact time, relying, for example, on NTP.
Further assume that asterisk is installed, but if it is not, then there are a lot of materials on this topic. We will also assume that the initial setup of at least one SIP phone or softphone has already been made.

The syntax is quite simple and the rule is the same if the input data XX is any two digits. We play the file digits / mon- (XX-1), where (XX-1) is an arithmetic operation. With X = 02 (yes, it "digests" even such numbers, which will help us a lot), 02-1 = 1, digits / mon-1: "February".

What time is it now?
I think you should not even mention that your server should know the exact time, relying, for example, on NTP.
In a nutshell about configuring NTP
Time on servers has the property of being out of sync, if it is not let down. An ntp package is required anyway. For myself, I chose the first option with ntpd, since my other servers are failing within the network.
Option number 1 . Add servers to taste , depending on the region in which the asterisk is located. The faster the response from the time server, the more accurately it will be set, all other things being equal. I will choose the Russian pool.
Check that the daemon is listening on the right ports:
If you want to distribute time to your servers, do not forget to check the firewall, UDP / 123 port. The rule must rise before the final REJECT. Remember to save.
Option number 2 . For a one-time adjustment, the ntpdate utility, included in the same ntp package, is suitable. This option is suitable if the distribution of time from the server is not planned.
You can add to cron:
#yum -y install ntp
Option number 1 . Add servers to taste , depending on the region in which the asterisk is located. The faster the response from the time server, the more accurately it will be set, all other things being equal. I will choose the Russian pool.
#grep "^ server" /etc/ntp.conf server 0.ru.pool.ntp.org server 1.ru.pool.ntp.org server 2.ru.pool.ntp.org server 3.ru.pool.ntp.org #chkconfig ntpd on #service ntpd start
Check that the daemon is listening on the right ports:
#netstat -putln | grep ntpd
If you want to distribute time to your servers, do not forget to check the firewall, UDP / 123 port. The rule must rise before the final REJECT. Remember to save.
#iptables -nL --line-numbers #iptables -I INPUT 4 -s 10.0.0.0/255.0.0.0 -p udp --dport 123 -j ACCEPT #service iptables save
Option number 2 . For a one-time adjustment, the ntpdate utility, included in the same ntp package, is suitable. This option is suitable if the distribution of time from the server is not planned.
#ntpdate ru.pool.ntp.org 9 Oct 17:08:41 ntpdate [32744]: adjust time server 85.21.78.8 offset -0.183259 sec
You can add to cron:
#echo -e "\ n47 * / 1 * * * root / usr / sbin / ntpdate pool.ntp.org> / dev / null \ n" >> / etc / crontab
