I saw that, but I wasn't sure if that's what I was looking for. So then the remote TFTP server will need to have SMB/CIFS running.
I'll have to try that out.
Thanks!

In 4.x you could use the alternate TFTP path so that TFTP will write out configuration files to an arbitrary SMB/CIFS file path.
In later versions of CM there is also centralized TFTP where all TFTP files are now available via http as well so a remote server can download the files - point your web browser (not IE though) to http://<CM_TFTP_SERVER:6970/XMLDefault.cnf.xml

While we are talking about TFTP, is there an easy way to use an external TFTP server? We have a campus DNS/DHCP appliance that is fully redundant and we'd like to offload some of this from the voice servers.
Is there a way to ensure that CallManager updates the config files on an external TFTP server?

I have this feature in computers now, one PC downloads a virus/worm from the net and passes it among friends. Isn’t this how Cyberdyne from Rise of the Machines got started? Are we building Skynet? Selsius? Skynet? Both started with a S…. <grin>

In regards to your comment, “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.” ,,,where, when, how? Any details?
Thanks!

Craig,
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 (http://www.etree.org) 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.
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.

Router is definatly an option as I am part of the network group. However again this would mean that I or someone from my team would need to manage 350 different TFTP servers. One across each site. So not real scalable.
Wes maybe you know did cisco monkey with the TFTP times on the phones. The default for TFTP timeout is 1000ms however I have seen some people change this down to 200 or 300ms.

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