upgrading firmware cisco callmanager linux

I need to upgrade the firmware for a Cisco 7940 in Cisco CallManager 6.1 Linux addition. I need access to the tftp directory, however I cannot ssh into the linux distro and not sure how to administer that. I have the Admin password so the admin account does not work via ssh and I have a personal admin account that gives me full rights. I did not install the device and there isn't anyone around who has done this. Docs have been limited. Maybe I am offbase and there is a way via the call manager to do this via the app, I dont know. Anyone have experience doing this?

how about using another tftp program----like solarwinds tftp?

Well because right now there are about 500 phones and I would have to change the profile to accommodate.  The phones get the tftp address from the options in the dhcp server so to have the new firmware in the default location would be key.
David Scott, MCSE

you're going to have to reboot all the phones for them to get the new firmware no?  

if so, change the dhcp options to point to a different tftp and put the new firmware there.  When the phone reboots, it will get the new dhcp info and firmware

you can't telnet  into the linux application?

there isn't anything in the cisco call manager admin software where you can configure the tftp?

Well I actually tried to telnet and ssh, but during a scan i noticed telnet isn't open. The realistic picture is I am piloting the sip firmware and I need to get a group of phones to register. The only way to do that is to upload the firmware. To change the dhcp options would be a nightmare because it would reset all of the phones. So if i update the sip profile and update the physical device with the new profile then it would only effect those devices. The only real solution would be to update the firmware which I would think would be common for anyone who has administered callmanager. However, I am going on day 3 trying to find out what I need to do. I didn't set the unit up and I do not know who did, but access to the OS has not been found as of yet.

yeah.  i'm certified on the Interactive Intelligence 3.0 SIP

no experience with call manager.  

if it came down to it----you could set the tftp server statically in a few test phones
