No nerd knobs that I am aware of. If you are getting all the ACKs back
then it sounds like the packet is getting corrupted in transit. I do
not believe the phones validate the checksum on every packet, but only
verifies the whole file reassembled. Can you send me a packet capture
of a phone at the remote location attempting to upgrade? Or can you
access a PC at the remote location and attempt to TFTP download the
phone load from the TFTP server? Check the md5sum of the downloaded
file against the md5sum (<a class="moz-txt-link-freetext" href="http://www.etree.org">http://www.etree.org</a>) of the original file.
If you are using a PIX at the remote site you can use the packet
capture feature of it to remotely perform the packet capture. I can
reconstruct the payload from the packet capture and verify if it is
corrupt in transit.<br>
<br>
You will greatly benefit from an upcoming phone feature where 1 remote
site phone downloads from TFTP server, then the phones pass the load
among themselves.<br>

Well, you can always use the router as a tftp server; is that an option?<br>
