Hi AyoDeji,

Hi AyoDeji,

Need your assistance as I tried 

m installed tftpd on my PC and given and downloaded the firmware 8.5.3  from cisco website for 7945 IP phone

I have taken a spare switch wherein I configured the default settings as per below

interface Vlan1

ip address 192.168.11.1 255.255.255.0

ip dhcp excluded-address 192.168.11.1 192.168.11.20

!

ip dhcp pool 40

   network 192.168.11.0 255.255.255.0

   option 150 ip 192.168.11.22

   dns-server 192.168.11.4 192.168.1.4

   default-router 192.168.11.1

and checked the IP assigned to the Laptop its getting IP Address as 192.168.11.22

Now I connected Faulty IP Phone to other port of the switch and tried to open the tftpd64 fro the PC am able to see some file transactions happening on tftpd but Phone reboots after 3 mins and nothing happens after that

need to understand what's the problem attaching logs for your reference.

Need to understand where is the problem is am directing to the correct way or is there any configuration issue in either tftpd/Switch.

Please asist me as am having five 7945G IP Phones which are having this issue and need to push firmware in those IP Phones.

Re: Cisco 7961 IP phone showing blank screen after factory reset.

You are a life saver bro ! keep representing Naija positively..... A simple detail i missed was the base/default SCCP firmware. it was written on the Cisco 7942G. After identifying the correct firmware, i loaded it via TFTP and 50 dead phones came back to life.
