How is everyone handling this? (esp. in the MAC and LINUX environment)

We have an enormous installed base of IP phones, where the TFTP location was not programmed at the time of installation. ( the installed base at this point is virtually all SV8100 IP sets of various flavors)

I guess question 1 would be:
- have any of you found a way to push the TFTP location along with the DHCP request when the phone boots?

question 2:
- I'm using the latest ver. of IP phone programmer (7.2.1) but it requires Windows based machines on-site

Maybe, let me ask the question or address this subject more generally:
- how is everyone updating their IP phones' firmware at customer sites? (keeping them at the current F/W ver.)

Unless there is an overriding reason, such as a bug fix or as part of a larger upgrade, we will normally leave the phones at their current version. If we do have to perform an upgrade to the phones, and there is no ftp or tftp server in place, the option is to run pumpkin or tftp32 from the techs laptop and use IP Phone Manager to force the phones to download the new boot and program file.
