| Q: Incorrect Time On 230 and 560 Shortel phones Incorrect time is displayed on phones that are rebooted...both HQ server and contact center have correct time... Where do phones recieve their NTP? A: This is a pretty common issue. The phones will get ntp from the ntp address setting either manually set or via dhcp. If the time/date are way off - like months: You can view the info on the phone by pressing mute then 4636 #. Toggle through the settings until you see the ntp server address and make sure its set and accessible from the network. If time/date are just an hour off: 1. Check that the ntp setting from DHCP server has the correct time zone. Cisco's for example can be set with a time zone. 2. Check that your director server and/or time server have the latest DST patch from Microsoft. (HC) HostCheetah.com (VG) Virtual Graffiti |

| How to set the Shoretel server itself up as the NTP time source. Once you have set your Shoretel server as the NTP source, you can then use the NTP options for your Shoretel DHCP scope to set your phones to point to your Shortel server for time. Below are the steps we used to resolve the time issue. After setting the NTP source as our Shoretel box, the phones started correcting their display time after refreshing. Steps to set your Shoretel server as the NTP Source The below steps need to be performed on the Shoretel server itself. Change Server Type to NTP: *NOTE* This may already be set to NTP Registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type Modify “Type” to value of NTP, then select OK Change AnnounceFlags:*NOTE* This value may be set to “A” change to “5″. Registry subkey: HKEY_LOCAL_MACHINESYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags Modify “AnnounceFlags” to value of 5, then select OK Enable NTPServer: *NOTE* This value may be set to “0″, this needs changed to “1″. 0=disable, 1=enable Registry subkey: HKEY_LOCAL_MACHINESYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer Modify “Enabled” to value of 1, then select OK Specify Time Source: *NOTE* This value may be set to 132.163.4.102,0×8, change this to 192.168.1.1,0×1. (The IP listed is for reference. Change this to your Shoretel IP address). Registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters Modify “NtpServer” to value of 192.168.1.1,0×1, then select OK Select Poll Interval: *NOTE* This value was set to 604800 – We changed this to 900 (15 minutes). Registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient\SpecialPollInterval Modify “SpecialPollInterval” to value of 900, then select OK Configure Time Correction Settings: *NOTE* This value was set to 54000 – we changed it to 3600. Registry subkey: HKEY_LOCAL_MACHINESYSTEM\CurrentControlSet\Services\W32Time\Config\MaxPosPhaseCorrection Modify “MaxPosPhaseCorrection” to decimal value of 3600, then select OKRegistry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\MaxNegPhaseCorrection Modify “MaxNegPhaseCorrection” to decimal value of 3600, then select OK Quit Registry Editor Open Command Prompt (or you could reboot your server) At CMD, type “net stop w32time” then Enter At CMD, type “net start w32time” then Enter Source: http://web.computer-howto.com:8880/2012/01/shoretel-phones-showing-incorrect-time/ |
