No TFTP server on phone

[James Hawkins]

Hi,

I am working with a customer to upgrade a CUCM 7.0 cluster to 9.1(1a).

As part of this I am trying to upgrade the firmware on phones connected to the 7.0 cluster to the default version for 9.1(1a)

The have some 7942G phones in a remote office which I have not managed to upgrade. The phones are registered to the cluster and can be reset via the CUCM interface but they will not load the new firmware version specified in the Phone Load Name field.

Looking at the network page of the phone web server I noticed that the fields relating to TFTP are blank -see below. I cannot remember ever seeing this and I am not sure how the phones managed to register.

Anyone got any ideas what is happening?

Hi,

Check that option 150 is set on the DHCP server scope for this subnet.

I got to the bottom of this.

The customer bought some new phones, configured them at their head office (where the DHCP scope has option 150 set) and then sent them to the remote office.

They were able to boot up using the local DHCP scope which does not have option 150 set and managed to register with the CUCM cluster. However the phones are not able to receive any updated config or firmware via TFTP.

I have found some phone remote control software and will try manually setting the TFTP server configs on the phones.

As Alex said, you could apply the Option 150 to the local DHCP scope. Are the phones in their own Voice VLAN or are they takin a lease from the sites Data VLAN range?

Hi JAmes,

Can u also try doing telnet to call manager followed by tftp port from remote site PC  to check whether tftp port is opened or not? you would get a blank screen which would be stable with blinking cursor which means port is working.

telnet PUB IP address 69

regds,
