Hi:
I'm fairly experienced in networks, etc. but not that much in VoIP... so please bear with me. Long story short-> we have a couple of hundred Polycom SoundPoint IP 320/330 and 321/331 installed across our network. They are working but are managed by our current VoIP provider. As we are looking to change providers I took a look at the phones and found that they are running a bunch of different firmware versions which makes a nightmare to configure and manage. So, I'm trying to have them all set the same way.
Looking at the firmware table:
https://downloads.polycom.com/voice/voip/sip_sw_releases_matrix.html
I see that the latest firmware for the 321/331 is 4.0.15.1009 and that for 320/330 is 3.3.5. I set up a local TFTP server and started updating the phones but a lot of them did not get the updates (and I see them hitting the server for the files).
I also see that the BootROM can (and in some cases has to) be updated. But I can't find what is the latest version that works on each phone (and more importantly where to download it).
I'm hoping that by updating the BootROM all the updates should go thru. Any advice on where to get them? I realize the phones are old, but they are in good working order.
