how to install sip firmware on cisco 7942 and 7962 ip phone

:Things We Need

-tftp server and dhcp server (tftpd32)

-lastest sip firmware for phones from cisco


connect phone and pc to network without another dhcp server

extract firmware to tftp root folder

setup dhcp server with option value 66 for tftp address (if uses 150 ,it cause external tftp server address)

reset factory phone by holding # while powering on ,then after 5 second enter (123456789*0#)

now phone rebooted and search for dhcp and tftp server and began of upgrading

  • *for configuring (such as name user pass etc) should create a SEP************.cnf.xml which  should replaced with mac address of phone i give an example in below

*my phones come with sccp 9.3.1r1 firmware so the 8.5.4 firmware doesnt work on it

*firmware above 9.x only work with sip tcp protocol and need this config on both asterisk and phone:


transport=udp, tcp

N.B. It must say _exactly_ USECALLMANAGER





#Soft Reset

The code for the soft factory reset is: 123456789*0#
A soft reset does the following:
5. deletes key files on the phone including /etc/
6. reboots
7. phone recovers default loads file from TFTP server

#Total Hard Reset

The code for the total hard reset is: 3491672850*#
A total hard reset formats /flash0 blowing away everything except CNU. All settings and personalization of the phone is removed.

#Hard Reset with Network Setting Preservation

The code for the network preservation hard reset is: *7412369#085
And it also does a complete format of /flash0 — yet it preserves the network settings so that after the format, any static IP and other network settings are preserved. The settings are stored in volatile RAM, so it is important to not remove power to the phone during this process.

how to enter hp smart array setup

Press Ctrl+S to open the Intel Boot Agent Setup Menu. Press F8 to open the ROMArray Configuration menu. From the Main Menu, select Create Logical Drive and press Enter. Select all physical disks under Available Physical Drives.



Assuming you’re on a recent firmware revision for the DL320 G6 server. You’re going to have to pay close attention to the POST messages in order to catch the RAID controller’s ORCA utility prompt.

The “Sea of Sensors” POST routine takes awhile from the first screen prompt (on a warm-boot) to step through RAM checks and to register the sensors. After the ambient temperature display, you will receive a prompt to “Press any key to view Option ROM messages” – Press any alpha-key on the keyboard at this point.


From there, you’ll see a prompt for the ILO 2 configuration menu and then, you’ll receive a few options for your Smart Array controller. Press F8 to enter the ORCA screen. You can configure a logical drive there.

how to block usb in active directory for users or computers


after searching whole internet for a tutorial to block usb devices in active directory i found that non of them are actually work because in all of them they said to

“enable (* removable access * deny) in computer config/administrative templ

and link existing gpo to USER or OU

then run gpoupdate /force command in both server and client

and poof not working

because they point to enable usb blocking in computer config so then we shoud link gpo to comuter instead of users

while doing that make usb blocking work perfectly but also block usb for every user on that particular computer included administrators

so what to do to block usb for users instead of computer?sample just:

enable gpo in user config/ instead


also if your AD functional level is windows server 2000 the android smartphone and other portable device is still have accessable to avoid that you need to raise it to 2012 r2.

be notice with that windows xp and older mashine maybe stop working in AD

which as below:
first copy downloaded driver to datastore from esxi win client or web client or sap software (like winSCP)
the put server in maintenance mode by client or the following code:
> esxcli system maintenanceMode Set —enable true
then copy copied file to /var/log/vmware path
