I've setup a new UC320 after ungrading to 2.1.1 and all works fine except the 5252G2 resets approx every 2 minutes with this diaglog on the screen. I have not tested this phone on a previous version of UC320 software.
"Refreshing voice component"
The phone is running
software version 7.4.4
Hardware version 2.0
The 525G has also been reset to factory defaults before being automatically added to the UC320
Another connected SPA504G doesnt reset and behaves normally.
I'll suggest a couple of troubleshooting steps:
I believe the phone should be on 7.4.8, but that is managed automatically by the UC320W. You should use Ethernet to do the above steps. When finished you can go WiFi if you choose. Hopefully, these steps will help.
I found that upgrading the 525g to software version 7.4.7+ as well as following the above steps will get the phone to recognize the UC platform in the hardware discovery step of the GUI. Definitely want to make sure your UC firmware is 2.1.3 as well.
I was troubleshooting this problem recently for a client and came across this thread. My client had a UC320 & recently purchased 2 SPA525G phones to work with it. Both phones exhibited this problem: every 2 minutes, the phones would report "Refreshing Voice Component", followed by "Resync in progress" and finally "Resync completed". Talking with Cisco support, the problem turned out to be the SPA525G phones were a newer hardware revision that the UC320 couldn't successfully talk to, so the UC320 was repeatedly trying to re-provision them. The SPA525G phones that are incompatible are the ones with 128MB of flash memory, as opposed to the models that had 32MB of flash. The easiest way to tell if you have a new phone is by serial number: SPA525G phones that have a serial number greater than CCQ18160L03 have 128MB of flash. Serial numbers earlier than that have 32MB of flash, and are compatible with the UC320.
I have exactly the same problem :-( I'm a user of UC320W and have 12 phones SPA525G working correctly. I bought 2 pieces a few days ago and both restarts showing 'Refreshing Voice Component ...'. Is there any solution for this?
Please, help me with this. My Cisco reseller does not want to accept the return phones from me :-(
Hi - have you been able to resolve this issue?
I ran into the exact same problem, and I am pulling my hair out! Have you come across any workarounds or fixes?
There's no good way to resolve. UC320 require particular firmware version to be running on phone, but your phone of particular hardware revision is unable to run it.
Remember - the UC320 is EOS/EOL already, thus there's no attempt to make new hardware revisions of SPA525G2 compatible with it.
Those new revisions of SPA525G2 can be connected as generic/unsupported SIP devices only.
Dan_Lukes Thank you. I appreciate the fast comment. It's disappointing, but it is what it is. Any recommendation on a good UC320W alternative?
There is Business Edition 6000 from Cisco, but it's not true replacement for SMB segment - it doesn't support SMB phones. IMHO Cisco have no suitable solution for small business segment.
Consider third party SIP PBX instead of Cisco's proprietary Call Manager. SIP is standard protocol, so even if you will replace PBX for whatever reason, you need not to trash all phones - and vice versa.
