i firstly tried to install the cisco ip phone 7942G model. but while i try to change the LAN configuration its showed unlocke.
so i tried to restore the factory settings which is available in cisco guide.
after i did the factory settings its got struck up at upgrading screen. after that no process happen. wait for more than one hour.
kindly give the solution for the above probelm..
also what is the default password used in cisco ip phone for administratie purpose.
thanks in advance.
Is DHCP enabled for the phone and DHCP server reachable from the phone network.
Factory rest phone requires DHCP to boot.
Your phone probably must have lost the firmware.
no problem just check the ip the phone gets then restore the firmware using tftp server while giving option 150 so that phone knows where to contact for the tftp.
actually if i on the Ip phone.. its showing front screen as "Upgrading" message and some mac address.
after that its not processing. its hang up to that state....
whts the version in the device default configueration in call manager??
also whats the device load on the phone?
looks like you need to perform the bridge upgrade
connect ur ip phone & pc to a POE switch just download the firmware of the ip phone place it in the directory of the tftpd32 browse and show the folder, go to settings in dhcp server give starting ip and a range then add additional option as 150 then unplug the phone and replug it then the phone gets to know that it needs to contact tftp server for firmware upgrade and it automatically downloads the firmware it takes like 5-7 minutes and dont unplug the phone until it boots up properly.
As you said DHCP is enabled on Phone.
I wanted to ask, is you phone reaching DHCP server for the IP address. And is DHCP server reachable.
