[Asterisk-Users] FW: Cisco Firmware Upgrade TFTP time out problems.

[Tom]

James,

Just did it today with a Linux tftp server.  Spent a good part of the day 
figuring it out.  Started with SCCP image of 3.0 I believe.  We had to use 
SIP 2.3 to 4.4 to 5.3 to 6.3.  We could not get 5.3 to take.  We were 
missing the 4.4. step and I believe it had to do with a documented bug in 
the file size.

Contact me off-list if you need more info on this and I'll get it to you 
tomorrow.
