[Asterisk-Users] 7940/60 TFTP Problem

[Paul Mahler]

If they are older phones, you may need to upgrade to version 2.3 before
upgrading further. Get a copy of the document "How to Convert a Cisco
7869 CallManager Phone to a SIP phone and the Reverse Process" from the
Cisco Web site.

I was wondering if anyone else has had this problem.  I have purchused
several Cisco 7940 and 7960 phones.  Of the 5 phones so far I have run
accross 2 that that give me malformed TFTP and refuse to upgrade to the
latest version of SIP code -- 5.3.  In fact some of the other phones
also give malformed packets do this but they seem to work OK.  The ones
giving me the problem when looking in ethereal are misiing part of the
filename to get it upgraded to SIP.

I know why it does not work, but why are these malformed packets
apearing.  I also tried to go to a windows based TFTP server (original
was linux TFTP) with the same results.

Any ideas anyone?
