I have a pair of 8700s running CM3.1.2 and have some 4621SW phone sets with the VPN firmware on them for home use. I notice on the VPN firmware that the boot file is b20d01b2_3.bin but the same phone on my desk has the latest boot file of b20d01b2_8_3.bin. Is the older boot file specific to make the VPN phone work or can I upgade it on my VPN phones to the lastest and leave the application file alone? I guess I'm asking if the VPN phone will work with the latest boot file and.
Thanks
