Update TFTP Address on IP Communicator

Hi Voice team, i change the CUCM on my company to version 9.1.

I had to change the ip address, the problem is that now I have more than 100 ip communicator, how do I dynamically change the TFTP address that is registered?

Thanks,

Thiago

Hi.

The windows registry key mentioned by Chris is HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems Inc.\Communicator

TFTPServer1 (the ip address is written in decimal or hexadecimal)

It is stored in the registry, so if you can push the registry update it would be the easiest, assuming you are not using default and pulling it from DHCP scope.

Just to add to excellent suggestions by Chris and Carlo (+5 guys), the hexadecimal values is read backwards..

eg..here is the hex value of my tftp server in the registry

e01fa8c0

e0=224

1f=31

a8=168

c0=192

so the ip will be

192.168.31.224

Thanks,

You need to convert your ip to hexadecimal...You can use this link to convert hex to dec or dec to hex

I made the conversion from my new ip 1047286 and the hex is ffaf6, i put on TFTP parameter, but the ip communicator

did not change the address.

That conversion is wrong..can you confirm that your ip address is 10.4.72.86? I will do the conversion for you

Not really..I am running Windows 7 and I didnt need to restart my mahcine. Ensure you exit the IP communicator and start it again, if it doesnt still work, try and restart it

It works only on TFTP 2, on TFTP 1 still the old ip address on IP communicator

Update TFTP Address on IP Communicator

Ensure you have entered it correctly...If it works on one, it has to work on the other--or restart the pc

I realized I have some computers that have IP communicator but does not have the option TftpServer1 and TftpServer2 Communicator, I tried to create the registry but did not work.

Thanks,

Update TFTP Address on IP Communicator

Hi Thiago.

In that case you should change two registry keys.

Put AlternateTftp key to 1 (the path is the same that i specified above)

and modify TftpServer value as above

Hi.

I would also add that only IP Communicator should be resterted  to make valid registry changes both on Win7 and XP.
