Hello all
I'm wondering how to set the time on ip phones automatically using ntp/sntp. Do I just set the 7000 device to get time from an Internet time server and then the phones will automatically get time from the 7000? Phones are not displaying the correct time.
I appreciate the help
Thanks
gerardo,
There are two pieces that need to be accounted for to make this work:
1 – Setting up the 7100 to be an SNTP server as well as to sync to an external SNTP server:
CLI example configuration:
!
ip name-server 4.2.2.2 4.2.2.1
ip sntp server
sntp server time.nist.gov
!
Daylight Savings Time will automatically be accounted for with following command. This is enabled by default:
clock auto-correct-DST
2 – Set the phones to get their time from the 7100:
Polycom phones get their time settings via DHCP.
CLI example configuration:
!
ip dhcp-server pool "VoIP_pool"
ntp-server 10.10.20.1
timezone-offset -6:00
!
Note: Replace “VoIP_pool” with the name of your specific DHCP pool serving the phones, replace 10.10.20.1 with the IP address of your NetVanta 7100, and -6:00 with your applicable timezone offset.
IP 700 phones get their time settings from individual phone configuration files or globally from the adtran_customer.txt file.
SntpServer 10.10.20.1
GmtOffset -0600
Note: In R2 firmware the IP 700 will also get time settings from DHCP, just like Polycom phones. Also, make sure to save your configuration.
I hope this helps.
Thanks,
Matt

Hello all,
My office Installed Netwanta 7100 and Polycom IP 335. Initially time and date is not correct. I follow the above procedure Date is changed well. But the time is different one hour.
Example: Singapore current time is 10.00 am. But my IP 335 phone shows 11.00 am. Please advise. thanks.
Hello All,
I got it. Polycom IP phones all come with default is Day light save timer is enabled. Manually login(Web Gui) the Polycom IP 335 and disabled the Day light save timer . After disabled the DST, change to right time now. Thanks all.
I was going to suggest that. I'm glad it worked
