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 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><BR>/Wes<BR><BR>Craig M Staffin wrote: <O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="MARGIN-BOTTOM: 12pt"><FONT face="Times New Roman" color="black" size="3"><SPAN style="FONT-SIZE: 12pt"><BR></SPAN></FONT><FONT face="Arial" size="2"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Router is definatly an option as I am part of the network group.
