Have got the following from Cisco site:






The converting process states that I need 4 files namely:





Cisco wont allow me to download these files. Is there any other place I can get it. Here is the details of my current 4940 IP phone

Host Name SEP001BD52C578B

Phone DN 5299

App Load ID P0030301MFG2

Thanks for your help

I don't think these files are needed for firmware conversion, ignore them or supply empty ones. Later on, you can configure them for further personalization.

Manage to change that. On Firmware status it now says

Application Load ID


Boot Load ID


My Asteriks box IP is my number is 4002 with my password 2004

Thanks for your help

How do I reset all the configuration of this phone to the factory default settings ?

Power one while pressing #. Release when display "reset sequence dtected". Press 12345689*0#. Press again 2 to confirm network settings erase.

This will erase also the firmware, so you must have DHCP and TFTP server correctly configured to provide firmware again to the phone.

Hope this helps, please rate post if it does!

Did try that and didnt get that message "reset sequence dtected". Did recycle the power while pressing #. IT go straing into configuring VLAN and then configuring IP then back to the normal phone display
