I’m trying to edit the configuration of cisco cp-7821 cnf.xml file to make the timezone for Asia/Baghdad, but to no avail, the code is below:

  <dateTimeSetting> 
     <dateTemplate>D/M/YA</dateTemplate> 
     <timeZone>Arabia Standard Time</timeZone>
     <ntps> 
        <ntp> 
           <name>pool.ntp.org</name>
           <ntpMode>Unicast</ntpMode> 
        </ntp>         
     </ntps> 
  </dateTimeSetting>

I also have an NTP server with IP address 192.168.50.1
how do I set the phone to take time settings directly either by ntp.org or the NTP server I have configured?
