I run my business from home and I actuallly got stuck on how to configure the IP telephony at my home. I need your support to configure this at home. I have the following hardwares and services:

1. Internet connection (wireless + LAN)
2. Netgear dg834gv v2 router
3. VOIP service with Engin company (Australian)
4.Cisco CP-7945G IP Phones 7900 series Colour with SIP support

I'm newbie to this and your support is highly appreciated.

    Do you have your network configuration settings?

    You should be able to apply them through the menu - the button that looks like a page of paper - or maybe a planet (depending on your phone)

    Go to network configuration to setup the necessary info.

    If it is locked, try pressing **#

    This usually unlocks the configuration lock on Cisco phones.

    step 1
    Get a tftp server software.

    Now the important part comes..creating configuration files...i have searched a lot in google for configuration files..hav not seen here i am putting the formats of those configuration files.

    These are the files required.
    1.CTLSEP001121F11A5A.tlv ( 001121F11A5A is mac address of cisco ip phone)
    3.P0S3-8-12-00.sb2 (name of iso image)
    7.SEP001121F11A5A.cnf.xml (MAC address of cisco phone after SEP)
    8.SIP001121F11A5A.cnf (Mac address of cisco ip phone after SIP)

    now the contents of these files

    1. CTLSEP001121F11A5A.tlv this file shouldn't have any content in it.You can create a file like this
    using the free hex editor Neo and save it in the above name.

    2. The OS79XX.TXT file should contain the name of the image like the following one :


    3. please note except 1st and last three files others will be der in the zip file which u gets from CISCO.

    So i am going to 7th file SEP001121F11A5A.cnf.xml the following should be the content of this file :

    pls dont forget to edit the name of ios as the one ios u r having.
    4. now the content SIP001121F11A5A.cnf
    (change image name as of the IOS one u are having in image version field.)

    telnet_level : 2

    add the above underlined things as of your requirement.
    if u have outbound proxy ..please add that too in the mentioned place in the above file.

    5 Now the content of SIPdefault.cnf file.

    #Image Version
    image_version:P003-8-12-00 ;

    #Proxy server address
    proxy1_address: ip address of your voip proxy server ;

    add image version and voip server ip
    So after creating these configuration files put these files together with 5 files which u will get with image file from cisco in tftp root file.


    you should have a DHCP server in your netwrok.i have used dhcp server which is der in my primary domain controller network,If u does not have one u can install windows 2003 and create one dhcp server in ur we have to add option 150 in dhcp server

    After adding option 150 -right click scope option - configure options - put a tick in the newly added tftp server ip address and add ip address of the pc in which u have installed TFTP SERVER apply and press ok.

    Start the TFTP SERVER .

    Connect your cisco phone to LAN and reboot it. please note that dont reboot any other cisco phones at this time, because it will also try to get files from tftp server.

    now the cisco phone will get connected to TFTP server and will take configuration files and image file from tftp server.

    If you does not have image file , you can download it from cisco directly.but you should have account in cisco , also you can check
