Why IP need to know its information phone of VLAN?

Why phone IP need to know its VLAN ID?

Hi Fayiz,

First, you use IP phones that runs on IP addresses... and on the same switch port that is connected to the phone and as well as a PC... you need to differentiate the two ip packets so to what this should be another subnet lan for all devices of IP phone and the different subnet to the data... as well , all data packets will cross via the package of data vlan and the voice through the vlan voice.

So, in this case an IP phone should know what is its id vlan, then it can send the packet to its vlan corresponding...

So, every time we using IP phane and pc on the link L2 then we will differentiate it by managing the different VLANS for voice and data package.

This is why it is very important for an IP phone to know its id vlan.

Hope this will be useful for you...

Please do not forget to rate if you find it useful for you.

Kind regards

    Original title:

    Windows 7 no sound at all

    Hello

    I would like to ask help for Win 7 problem 'No audio '.

    I have a Win 7 64-bit Professional desktop PC. It has a motherboard Asus P5Q - EM.
    Previously, everything worked very well over a year, but now there is no sound at all. I see a little red x in addition to the speacer icon.

    I got a craphics card problem and it has been replaced, and shortly after, I didn't notice that no audio problem.

    First of all, I tried to fix the external audio card drivers - no help. Then I thought to use the motherboard
    audio only and removed the external audio card. I have cheked Bios that there is audio compatible motherboard.
    Windows Manager device shows Audio Realtek High Definetion. (Once I reinstalled externally
    audio card, but did not get it to work and I deleted again and focused on getting the Audio motherboard
    work.)

    Through the Device Manager, I uninstalled the device Audio from Realtek motherboard and all other audio related devices and start the PC.
    After you start Windows 7 detects audio devices well and tries to install the drivers but still said the driver installation failed.

    I also used the troubleshooter in Windows 7. According to the material and audio, I clicked on the audio playback troubleshooting. The system has tried to install the drivers, but all have failed in similar way as after rebootig.

    When I go to see the Audio the Realtek High Defenetion properties, it says:
    Windows cannot start this hardware device because its information of configuration (in the registry) is incomplete or damaged. (Code 19)

    I downloaded the latest drivers (some 54 Mb file called: 64bit_Vista_Win7_R267) Realtek www-site and run it, but no help. Same problem - no sound at all.

    If I run application system information and go to the "components" > "Problem Devices", it is said Realtek High Definition Audio, error code: failure using the VxD loader. It is also noted on the VAN Miniport (IKEv2), error code: this device does not work properly because Windows cannot load the drivers required for this device.

    I also unplug the beam of the motherboard front audio jack. I thought it may create a connector related issues, but he did not make a difference.

    If I ask the system to update the driver using Device Manager, it says that the piloted is up-to-date.

    I checked the details Realteck Sound Device in the Device Manager and it says under the number "Problem code" 13.

    Also other devices under device 'Video controls and sound game' managers do not work. I uninstalled all the. After reboot Windows 7 detects all the. Win 7 tries to install the drivers, but always fails and yellow! singing appears next to all devices.

    Under the NIC in Device Manager there is another device with the yellow! sign as well. The WAN Miniport (IKE v2). I don't know if it has something to do with this audio problem? Win 7 detects it as well after uninstalling and tries to install drivers after the start, but is also always fails.

    Now, I'm confused and I don't know if the problem is really in the Windows registry database? What is error code 13 of Realtek Audio device and what is actually the VxD loader problem?

    I'm completely lost on how to proceed with this problem.

    Can someone give advice on how to continue with this question...

    I plugged the the hardware id in the Microsoft Update Catalog and the device is identified as a C-Media CMI8738/C3DX PCI Audio Device but there only Windows 2000/XP drivers available through Windows Update (you need to install the ActiveX control to view and download the drivers):

    http://catalog.update.Microsoft.com/v7/site/search.aspx?q=PCI%5CVEN_13F6%26DEV_0111%26SUBSYS_011113F6%26REV_10

    Connect the hardware id PCIDatabase provides a link to C-Media (one-third to the bottom - device ID 0 x 0111):

    http://www.PCIDatabase.com/vendor_details.php?id=376

    However there are a of the drivers mentioned in the following link that can run, and I suggest to try:

    http://www.SevenForums.com/sound-audio/9824-c-media-Freezy-my-PC.html

    The driver is the "Striker 7.1 pilot" (striker81742.zip) in the following link:

    An in these drivers .inf file has an id of material corresponding to your device.

    I recommend the creation of a System Restore Point before trying new drivers.
