Hi Guys, I have a problem on our deployment. Here's the scenario: We  have deployed VOIP using SIP with 7962, 7942 and 6921 phones. We using  2N Netstar to act as our Call Manager. For addressing, we use DHCP which  also gives the TFTP server address. Every configuration text file and  things needed on the default loads file are on the TFTP server on a  CentOS VM. Aside from the issues on NTP and Corporate Directory on 6921  phones, everything is working fine. Regarding the Corporate Directory, since we are not using Call Manager on our deployment, I have uploaded an xml file on a web server which contains the directory entries. I have changed the following settings on the xml file. <directoryURL> http://192.168.4.10/dir.xml </directoryURL> and </phoneService> <phoneService  type="1" category="0"> <name>Corporate Directory</name> <url> http://192.168.4.10/dir.xml </url> <vendor></vendor> <version></version> </phoneService> These same settings were used on both 6921 and 79xx phones. I have tested the directory on the 79xx phones and they work just fine. However, when I access the Corporate Directory on the 6921 phones, it just displays "File Not Found". I have checked the status messages and no error message comes up. I am using firmware 9-2-2-7 for the 6921 phones and 9-3-1 for the 79xx phones. Any help regarding the matter is greatly appreciated. Thanks, Pai ... View more

Hi Guys, I have a problem on our deployment. Here's the scenario: We have deployed VOIP using SIP with 7962, 7942 and 6921 phones. We using 2N Netstar to act as our Call Manager. For addressing, we use DHCP which also gives the TFTP server address. Every configuration text file and things needed on the default loads file are on the TFTP server on a CentOS VM. Aside from the issues on NTP and Corporate Directory on 6921 phones, everything is working fine. Our client has set up a CentOS and Windows VM to be the NTP server. But the phones are unable to sync the date and time with it. The 6921 does not display any date and time, while the 79xx series phones consistently displays "5/16/2012 5:30" every reboot. I don't know where the 79xx phones get this. As a work around, I tried pointing the Netstar as the phone's NTP server. I changed the NTP settings on the xml file as shown below. <devicePool> <revertPriority>0</revertPriority> <name>Default</name> <dateTimeSetting> <name>CMLocal</name> <dateTemplate>M/D/Y</dateTemplate> <timeZone>Taipei Standard Time</timeZone> <ntps> <ntp> <name>192.168.4.1</name> <ntpMode>Directed Broadcast</ntpMode> </ntp> </ntps> </dateTimeSetting> <callManagerGroup> <name>Default</name> <tftpDefault>true</tftpDefault> <members> <member  priority="0"> <callManager> <ports> <ethernetPhonePort>2000</ethernetPhonePort> <sipPort>5060</sipPort> <securedSipPort>5061</securedSipPort> </ports> <processNodeName>192.168.4.1</processNodeName> </callManager> </member> </members> </callManagerGroup> </devicePool> Although the Netstar does not have a dedicated NTP server function, the 6921 phones are able to sync its date and time with the Netstar. However the 79xx phones are unable to sync. I am using firmware 9-2-2-7 for the 6921 phones and 9-3-1 for the 79xx phones. The default load file of the 79xx phones contain these files: jar42sip.9-3-1TH2-5.sbn cnu42.9-3-1TH2-5.sbn apps42.9-3-1TH2-5.sbn dsp42.9-3-1TH2-5.sbn cvm42sip.9-3-1TH2-5.sbn Any help regarding the matter is greatly appreciated.
