I have about 50 Poly VVX350 phones that are currently on version 6.4.3. The shop where the phones will be installed are on a T1 circuit. The newer version 6.4.5 is about 50mb. For the 50 phones it will take me an eternity. Is there a way that I could use a usb to download and install the 6.4.5 release on each phone? If not, are there any suggestions to run the upgrades less painfully? Thank you.
